+name: deploy
+description: Ship the colectivo stack to ambrosio (https://erosi.limonia.net) with pre-deploy DB backup, or roll back code + DB to a previous deploy. Trigger when the user asks to deploy, ship, push to prod, roll back, or undo a deploy.
+---
+
+# Deploy + rollback skill
+
+Deploys and rollbacks for the production stack on ambrosio. **Every deploy takes a paired DB backup first**, every successful deploy is logged with `(timestamp, git-sha, backup-filename)`, and rollback uses that log to restore both code and DB atomically.
+
+## Trigger
+
+Use this skill when the user says any of:
+- "deploy", "deploy to ambrosio", "deploy to prod", "ship it"
+- "roll back", "rollback", "undo the deploy", "revert prod"
+- "list deploys", "what was the last deploy"
+
+## What the skill does
+
+### Forward (deploy)
+
+1. **`just deploy`** runs `infra/scripts/deploy-erosi.sh`:
+   - Captures the local short SHA (`git rev-parse --short HEAD`).
+   - rsyncs the working tree to `ambrosio:/opt/colectivo/` (excludes `.git`, `node_modules`, `**/.env`, etc.).
+   - On a fresh `.env`, generates secrets and bails — operator fills `PUBLIC_KEYCLOAK_URL` + `KEYCLOAK_CLIENT_SECRET` and re-runs.
+   - **Pre-deploy DB backup**: `pg_dumpall` from the prod `db` container → `backups/predeploy-<ts>-<sha>.sql.gz` on ambrosio. Aborts the deploy if the dump is < 1 KiB. Keeps the newest 10 backups.
+   - Rebuilds the `app` image with `GIT_SHA` build-arg (so `__APP_COMMIT__` lands in the bundle, Fase 14.3).
+   - `docker compose up -d` brings the stack to the new image.
+   - Applies any pending DB migrations.
+   - On success, appends `<iso-ts>\t<sha>\t<backup-file>` to `/opt/colectivo/.deploys.log`.
+2. Site smoke: `curl -I https://erosi.limonia.net/` should return 200.
+
+### Reverse (rollback)
+
+1. **`just rollback-list`** prints recent rows from `.deploys.log` so the user can pick a target.
+2. **`just rollback`** rolls back code + DB to the previous deploy (last but one line of `.deploys.log`).
+3. **`just rollback-to <sha>`** rolls back to a specific deploy.
+4. **`just rollback-code`** rolls back code only, leaves the DB at current state — useful when the regression is UI-only and the DB schema is compatible.
+
+`infra/scripts/rollback-erosi.sh` enforces:
+- Confirms with a 5-second abort window before doing anything destructive.
+- Verifies the target SHA is reachable locally (`git cat-file -e`) and that the backup file still exists on ambrosio.
+- Materialises the target commit into a temporary `git worktree`, rsyncs from there, never disturbs the user's working tree.
+- Stops `app / auth / rest / realtime / storage` before the DB restore so they don't observe inconsistent state.
+- `gunzip | psql -v ON_ERROR_STOP=1` restores the dump.
+- Rebuilds the app image at the rolled-back SHA and brings the stack up.
+- **Does not** write a new `.deploys.log` line — rollback is intentionally not a deploy event.
+
+## Safety boundaries
+
+- The stack lives on ambrosio. The external proxy + TLS terminator are off-stack (`docs/deployment.md`). Neither this skill nor the scripts ever touch host TLS or the external proxy.
+- `infra/scripts/deploy-erosi.sh` never runs `sudo`.
+- `--no-verify` / `--amend` are never used. Pre-commit hooks must pass.
+- Always confirm with the user before invoking `just rollback*` — DB restore is destructive and irreversible.
+- Storage volume (`/var/lib/storage`, user uploads) is **not** part of the rollback. Treated as append-only.
+
+## What to tell the user
+
+Before running anything:
+- Show the local short SHA + branch + remote.
+- For deploy: confirm with the user. Mention "this will take a fresh DB backup before deploying."
+- For rollback: show `just rollback-list` output, ask which SHA, confirm destructive nature.
+
+After running:
+- Print the new `.deploys.log` tail (or the rollback target).
+- Curl-probe the site and report.
+
+## Files this skill touches
+
+- `infra/scripts/deploy-erosi.sh` — deploy, with pre-deploy backup + .deploys.log writing.
+- `infra/scripts/rollback-erosi.sh` — rollback, paired code + DB.
+- `Justfile` — `deploy`, `rollback`, `rollback-list`, `rollback-to`, `rollback-code` recipes.
+- `docs/deployment.md` — runbook for both flows.
+
+## Anti-trigger
+
+If the user is just asking *what would happen* on deploy (status, dry-run-style questions), DO NOT run anything. Answer from the script content.

+## [Unreleased]
+
+## [v1.0.0] — 2026-05-19
+
+First tagged release. Closes the v1.0 cycle (Fases 17–20): versioning + changelog tooling, the shopping-list creation flow rework, the emoji picker expansion, and Basque (Euskera) as a supported locale.
+
+- [new] Semver git tags + Keep-a-Changelog `CHANGELOG.md` in repo root, About modal in `/settings` renders the bundled changelog via `?raw` import, deploy script HEAD-tag check + tag column in `.deploys.log`, `scripts/check-changelog.mjs` linter wired into `just check` (Fase 17).
+- [new] Required list title + per-collective per-prefix auto-numbered `#N` parsed from the typed value, `collectives.default_list_title`, admin-curated `collective_list_titles` catalog with `add_list_title` / `remove_list_title` SECURITY DEFINER RPCs, autocomplete union (catalog + last-10) (Fase 18).
+- [new] Emoji picker expanded with full food + animals categories (~280 codepoints, Unicode 14 baseline for iOS<17 compat), new `EmojiPicker.svelte` with tabbed lazy-rendered grids replacing the 8-emoji hardcoded selector at 4 sites (Fase 19).
+- [new] Euskera (Basque) locale — `messages/eu.json`, `users.language` check constraint extended to `('en','es','eu')`, `accept-language` parser recognises `eu` / `eu-ES` / `eu-FR`, "Euskera" option in the `/settings` selector. Machine-translated seed flagged with `[needs review]` pending native review (Fase 20).
+
+## [v0.0.0-beta] — 2026-05-19 — MVP + MVP2 (Fases 0–16)
+
+Single rollup for everything shipped before tagging started. Covers the
+entire MVP cycle (Fases 0–7) plus the prod auth hardening pass (Fase 8)
+and the eight MVP2 fases (9–16). Reads as a feature catalogue, not a
+day-by-day diff — the per-fase docs in `docs/history/` and the per-fase
+plans in `plan/` are the source of record.
+
+- Auth + identity:
+- [new] Keycloak → GoTrue → Supabase OIDC integration (PKCE), with `auth.users` pre-seed for the 5 dev users (Fase 1).
+- [new] Self-registration via Keycloak; invitations are link-only (no email), generated on `/collective/manage` (Fase 1).
+- [new] Multi-collective per user with sidebar switcher; active collective persisted to `localStorage` (Fase 1).
+- [new] Atomic `create_collective(name, emoji)` RPC so onboarding works in a single round-trip without tripping `is_admin` / `is_member` policies (migration 012, Fase 7).
+- [new] Public `/logged-out` route + RP-initiated Keycloak end-session on logout, so the SSO cookie is actually cleared and the next login re-prompts (Fase 8).
+- [new] Account hard-delete (`delete_account()` RPC) with sole-admin auto-promote and a Danger-zone modal (migration 021, Fase 10.5).
+- [fix] `auth.users.role`/`aud` default-fill trigger so PostgREST routing survives the Keycloak provisioning path; INSERT + UPDATE both covered to defeat GoTrue's pop-ORM re-clobber (migrations 013–014, Fases 7–8).
+- [fix] `isLoggingOut` guard in `(app)/+layout.svelte` to suppress the auth-gate `$effect` during the logout navigation, closing a "PKCE code verifier not found in storage" race on prod (Fase 8).
+- [fix] `pendingInvitationToken` restored from `sessionStorage` after login so the user lands on `/invitation/<token>` instead of `/onboarding` or `/lists` (Fase 7).
+
+- Shopping lists + items:
+- [new] Lists overview (featured + grid + completed + trash) and detail view with checkbox toggle, qty stepper, inline edit, drag-reorder (Fase 2a).
+- [new] Frequency-driven suggestion chips on the add-item form, backed by the `item_frequency` table + trigger (Fase 2a; migration 006).
+- [new] Realtime "Modo Compra" full-screen session view with 56 px toggles, flip animation, complete-list → redirect; postgres_changes subscription per list with echo-deduplication (Fase 2b; migration 007).
+- [new] Offline-first sync queue (`SyncQueue` IDB-backed, FIFO flush, PK-conflict-as-success) with `online`-event auto-flush; offline/syncing banner mounted in detail + session views (Fase 2b).
+- [new] Selection mode with bulk delete / move / mark-checked, long-press entry on mobile + desktop toggle button (Fase 5.11).
+- [new] Reset-from-detail button on completed lists; "Crear nuevo colectivo" entry in sidebar + drawer (Fase 10).
+- [new] Trash drawer restore + hard-delete via `restore_list()` / `hard_delete_list()` RPCs (migration 020, Fase 10.4).
+- [new] Collective-scoped item tags (chips + picker + filter bar + realtime resort) backed by `item_tags` + `shopping_item_tags` (migration 022, Fase 11).
+- [new] Common-items management on `/collective/manage` — 3-way Hide / Normal / Boost segmented control writing `weight` via admin-only RPCs; suggestion strip reorders by weight + use_count + last_used_at (migration 026, Fase 15).
+- [new] Suggestion dropdown excludes names already on the active list (`excludeNames` capped at 200 to respect Kong URI limits) (Fase 15).
+- [tweak] Item row redesigned to `drag-handle | name-button | qty stepper` with swipe-to-(un)check; double-tap opens an edit overlay; `unit` column dropped because it became unreachable (migration 011, Fase 5.10).
+- [tweak] Add-form moved inline as the last child of the unchecked section; sticky bottom bars retired (Fase 5.14).
+- [tweak] List rename inline at the top of the detail view with 500 ms debounced autosave; "New list" button moved to the masthead (Fase 5.8).
+
+- Tasks + notes:
+- [new] Task lists + tasks with completion-consistency CHECK (`is_completed ⇔ completed_by ⇔ completed_at`) and drag-reorder (migration 008, Fase 3).
+- [new] Notes with 8-colour palette, pinned + archived (mutually exclusive), 7-day trash window enforced via RLS + `pg_cron` purge; editor with 500 ms debounced autosave (migration 009, Fase 3).
+- [new] Sync-conflicts review route at `/settings/sync-conflicts`, paginated, side-by-side local vs remote payloads, per-device dismissal via `localStorage` (Fase 14.2).
+
+- Search:
+- [new] Cross-section search via `search_in_collective()` SECURITY INVOKER RPC over generated `tsvector` columns on items/tasks/notes; debounced input, filter chips, deep-link per result type (migration 010, Fase 4).
+
+- Mobile UX + accessibility:
+- [new] Mobile shell — top bar with hamburger + collective name + avatar, slide-in drawer, bottom tab bar with safe-area inset, sticky contextual headers on detail routes (Fase 5).
+- [new] `UndoToast` for destructive actions (4 s TTL, auto-commit, mounted globally), with `scheduleUndoable()` queue (Fase 5).
+- [new] Spinner component (`sm/md/lg`, `currentColor`, `motion-reduce:animate-none`, sr-only label) integrated at 7 loading sites (Fase 16).
+- [tweak] Desktop reading width capped at `max-w-2xl` for content detail routes; mobile and `/lists/[id]/session` excluded (Fase 9.2).
+
+- PWA + offline:
+- [new] Installable PWA — Workbox precaching via `@vite-pwa/sveltekit`, manifest, iOS meta tags + apple-touch icons, placeholder slate-and-"C" icons (Fase 6.2).
+- [new] Service-worker auto-registration via `useRegisterSW` + 15 min `reg.update` poll; `UpdateToast` with "Reload" action when a new build is available; "Ready to use offline" auto-dismiss toast (Fase 14.1).
+- [new] `OfflineChip` in `MobileTopBar` + `DesktopSidebar` with a pending-ops badge when the queue is non-empty (Fase 14.2).
+- [new] Build-time version constants (`__APP_VERSION__` / `__APP_COMMIT__` / `__BUILD_TIME__`) exposed via `$lib/version`; "Acerca de" chip on `/settings`; `GIT_SHA` baked through the Dockerfile build arg by the deploy script (Fase 14.3).
+- [tweak] PWA strategy on prod switched to `generateSW` because `@vite-pwa/sveltekit` 0.6.8 hardcodes the source SW filename under `injectManifest` (Fase 6 → revisit in Fase 14).
+- [fix] `<link rel="manifest">` added to `app.html` so Android Chrome surfaces the install prompt (Fase 14 follow-up).
+
+- Collective management:
+- [new] Rename collective + change emoji (CU-H07) on `/collective/manage` (Fase 10.2).
+- [new] Leave-collective flow (CU-H06) with sole-admin auto-promote via `leave_collective()` RPC; sole-member rejected with P0001 (migration 017, Fase 10.1).
+- [new] Dissolve-collective flow (CU-H08) with type-the-name confirmation, via `dissolve_collective()` RPC (migration 018, Fase 10.3).
+- [new] Section visibility — per-user + per-collective `feature_flags jsonb` + `section_enabled()` STABLE SQL helper using COALESCE precedence (migration 023, Fase 12).
+- [new] Auto-detect language on first sign-in from `navigator.languages`, gated to fresh accounts (`<60 s old` + `language = 'en'`) (Fase 10.6).
+- [tweak] Every `created_by`/`updated_by` FK relaxed from `NOT NULL RESTRICT` to `NULL SET NULL` so a user delete cascades cleanly (migration 019, Fase 10.5).
+
+- Server admin:
+- [new] Global `server_admin` role (`server_admins` table) orthogonal to `collective_members`; `is_server_admin()` SECURITY DEFINER gate; bootstrap from `SERVER_ADMIN_EMAIL` on first DB init (migration 024, Fase 13).
+- [new] `/admin` route group with 9 SECURITY DEFINER RPCs (collective lifecycle, member removal, server-level section defaults) + append-only `admin_actions` audit log + last-admin guard (migration 025, Fase 13).
+- [new] `section_enabled()` extended with a server layer prepended to the user/collective precedence chain (Fase 13.2).
+
+- i18n:
+- [new] Paraglide JS messages for `en` + `es`, compiled at build time; `setLanguageTag()` flips the active locale without reload; selector on `/settings` writes to `public.users.language` (Fase 0).
+- [new] Search + collective-management + PWA copy fully localised in both languages across every fase that added user-facing strings (Fases 4, 10, 14).
+
+- Infra + deploy:
+- [new] Local dev stack — Docker compose with Postgres / GoTrue / PostgREST / Realtime / Storage / Kong / Keycloak; `setup.sh` for idempotent first-time bring-up; `Justfile` task runner (Fase 0).
+- [new] Production stack on ambrosio (OVH VPS) at https://erosi.limonia.net — `infra/scripts/deploy-erosi.sh` (rsync + first-deploy secret generation + every-deploy migration apply + pre-deploy backup + `.deploys.log` append) and `infra/scripts/rollback-erosi.sh` (paired code + DB rollback) (Fase 6 + later iterations).
+- [new] Kong rate-limit on `/rest/v1/collective_invitations` (20/hour per Authorization header) with `request-transformer` URI rewrite (Fase 6.3).
+- [new] JWT rotation script (`infra/scripts/rotate-jwt.sh`) + production env template + `rls-audit.sh` curl sweep + `just lighthouse` build-and-score recipe (Fase 6.4 + 6.5).
+- [new] Internal Caddy on `:3000` fans `/rest|/auth|/realtime|/storage|/graphql|/pg` → Kong, everything else → app; external TLS terminator (off-stack) forwards plain HTTP to ambrosio:3000 (Fase 6 → revision after prod cutover).
+- [new] Theme tokens stored as RGB triplets so `dark:` variants resolve consistently; three-mode preference (`light` / `dark` / `system`) persisted to `users.theme` + mirrored to `localStorage` with inline anti-FOUC script (migration 015, Fase 9.1).
+- [new] `sync_conflicts` append-only log + queue-side divergence detection so last-write-wins conflicts are auditable (migration 016, Fase 9.3).
+- [new] Pre-deploy `pg_dumpall` snapshot kept in `backups/predeploy-*.sql.gz` (newest 10) with paired code/DB rollback via `rollback-erosi.sh --previous` / `--to=<sha>` / `--code-only` (Fase 14 deploy work).
+- [fix] `docker compose exec -T` calls inside SSH heredoc deploys now redirect stdin per call so the surrounding heredoc isn't drained — silently skipped migrations no longer happen (Fase 8 deploy hardening).
+- [fix] PostgREST schema cache reload (`NOTIFY pgrst, 'reload schema'`) appended after every deploy and rollback so freshly-added RPCs are visible without a container restart (Fase 15 deploy work).
+- [fix] WebKit Playwright project gated behind `RUN_WEBKIT=1` so hosts without the GTK libs (libicu74, libwoff1, …) keep `just test-all` green; `*.webkit.test.ts` files excluded from the chromium project (Fase 9.4).

Post-fase-7 prod auth hardening (2026-04-20..21, see `docs/history/fase-8-auth-logout.md`): migration 014 extends the role/aud guard to UPDATE (GoTrue's pop-ORM resends role='' right after the INSERT and clobbered the INSERT trigger's backfill); `logout()` now does RP-initiated Keycloak end-session + lands on a new public `/logged-out` route, which both actually ends the Keycloak SSO cookie (so the next login re-prompts) and closes a PKCE-verifier race that produced "PKCE code verifier not found in storage" on prod. 259 tests green: 45 pgTAP + 140 Vitest integration + 15 Vitest unit + 59 Playwright + 1 Vitest rate-limit (gated, run via `just test-rate-limit`). 3 skipped in `just test-all` (2 Realtime presence — upstream `handle_out/3` bug; 1 rate-limit — gated).

UI 3-way segmented control (Hide / Normal / Boost → -50 / 0 / 50) in `/collective/manage` (admin write, member read-only, guest hidden). `fetchSuggestions` gains `excludeNames` (capped at 200 names to bound URL length on PostgREST `not.in.()` filter) to drop items already on the active list from the dropdown; see `docs/history/fase-15-common-items.md`. **Final test totals (`just test-all`): 177 pgTAP + 179 Vitest integration + 47 Vitest unit + 93 Playwright + 1 gated rate-limit = 497 tests green; 3 skipped (2 Realtime presence — upstream `handle_out/3` bug `supabase/realtime#1617`; 1 rate-limit — gated).

No DB migration; reuses existing `m.loading()`. Added 5 Vitest unit (SP-U-01..05) + 3 Playwright e2e (SP-E-01..03). Vitest config gained `resolve.conditions: ['browser']` + `server.deps.inline: [/^svelte/]` so Svelte 5's `mount()` resolves the browser entry; see `docs/history/fase-16-spinner.md`. **Final cumulative MVP2 (fases 9–16): 177 pgTAP + 179 Vitest integration + 52 Vitest unit + 96 Playwright + 1 gated rate-limit = 505 tests green; 3 skipped.**

+**Section visibility (feature flags) — required steps for any new top-level section.** A "section" here is one of the four current navigable areas (lists, tasks, notes, search) — adding a fifth means EVERY one of:
+1. SQL migration that updates `public.known_sections()` to include the new key + (if it adds a new RPC) maps onto the planned Fase 13 server-layer extension of `public.section_enabled()`.
+2. `SectionKey` union + `SECTION_KEYS` array entry in `packages/types/src/domain.ts`.
+3. Default-checked toggle row in `/settings` (per-user) and `/collective/manage` (admin) — both already iterate `SECTION_KEYS`, so this is automatic as long as you add the `section_label_<key>` Paraglide message + the route prefix in `(app)/+layout.svelte`'s `SECTION_BY_PREFIX` array (drives the redirect guard).
+4. pgTAP assertion in `supabase/tests/015_section_visibility.sql` that `section_enabled('<newkey>', user, collective)` defaults to true.

+- **WebKit (Mobile Safari) Playwright project is gated on `RUN_WEBKIT=1`.** Fase 9.4 added a `webkit` project (`devices['iPhone 13']`) for touch-gesture specs (the swipe-to-check/uncheck handlers use unified pointer events, but Chromium's touch emulation does not fire them in the right order). The project is conditionally included in `playwright.config.ts` based on `process.env.RUN_WEBKIT` so `just test-all` stays green on hosts that lack the GTK/WebKit system deps (libicu74, libxml2, libmanette-0.2-0, libwoff1 — install via `sudo pnpm exec playwright install-deps`). `just test-webkit` runs the gated suite. Specs named `*.webkit.test.ts` are also excluded from the chromium project via `testIgnore`, so a file never runs in both browsers.

 ### Backend / RLS / Kong
 
 - **`strip_path: true` on a full-table Kong route strips too much.** With `paths: [/rest/v1/collective_invitations]` and `strip_path: true`, Kong forwards `/` upstream — PostgREST returns `PGRST117: Unsupported HTTP method: POST` because it tries to route root, not the table. Fix: add a `request-transformer` plugin that `replace.uri: /collective_invitations`. Applies identically to any route where the match path equals the full upstream resource path (as opposed to a prefix match like `/rest/v1/`).

-**nginx (prod) — WebSocket for Realtime:**
-- The `/realtime/` location block **must come before** the `/` block.
-- `proxy_read_timeout 3600s` is required on the Realtime block — without it, nginx closes WebSocket connections after 60 seconds, forcing continuous reconnects during active shopping sessions.
-- CSP `connect-src` must include both `https://` and `wss://` for the API domain.
+**Edge proxy (prod):**
+- Two layers. Internal: a Caddy container on the `colectivo` Docker network listens on `:3000` (host port `3000:3000`) and does the path split — `/rest/v1`, `/auth/v1`, `/realtime/v1`, `/storage/v1`, `/graphql/v1`, `/pg` → `kong:8000`; everything else → `app:3000`. Config in `infra/Caddyfile.erosi`, mounted into `caddy:2-alpine`. Plain HTTP, no TLS, no Host matching. Global block sets `auto_https off` + `admin off` so the only socket is `:3000`.
+- External: TLS termination + outermost routing live outside this repo (originally NetBird's self-hosted Traefik on ambrosio, but the stack is proxy-agnostic now). Whatever fronts the host terminates `https://erosi.limonia.net` and forwards plain HTTP to `ambrosio:3000`. One upstream is enough — Caddy fans out internally.
+- External proxy must allow long-lived idle WebSockets for Realtime (≥3600s, or unlimited). NetBird's default is `0` (unlimited). Symptom of too-short: client reconnects continuously mid-shopping-session.
+- Bind-mounted files (Caddyfile, etc.) require `docker compose restart caddy` after editing. The deploy script's `up -d` only recreates services whose compose definition changed — a Caddyfile-only edit will silently keep the old config loaded.
+- CSP `connect-src` must include both `https://erosi.limonia.net` and `wss://erosi.limonia.net`.
 
-**Keycloak behind nginx:**
-- `X-Forwarded-Host` and `X-Forwarded-Port` headers are mandatory. Without them, Keycloak builds redirect URIs with the internal port (8080) instead of 443, breaking the OIDC flow.
+**External Keycloak:**
+- Keycloak runs outside this stack; `PUBLIC_KEYCLOAK_URL` in `.env` points at it. Whatever proxy sits in front of it must forward `X-Forwarded-{Host,Port,Proto}` or Keycloak builds redirect URIs with internal ports and the OIDC flow breaks — that's the external operator's concern, not ours.
+- The realm + client configuration required on the external Keycloak is documented in `docs/deployment.md` and mirrored in `keycloak/realm-export.erosi.json` (kept as reference; not imported by this stack). Realm name, client id, and client secret are operator-chosen and wired in via `.env` — the file's literal `colectivo-web` / `colectivo` values are illustrative, not required.
+- **Legacy Keycloak `/auth/` base path**: Keycloak ≤ 16 (and some later distributions) serve realms under `/auth/realms/...` instead of `/realms/...`. In that case `PUBLIC_KEYCLOAK_URL` must include the suffix, e.g. `https://auth.example.com/auth`. Symptom of a missing `/auth` suffix: `GOTRUE_EXTERNAL_KEYCLOAK_URL/...well-known/openid-configuration` returns 404; the Supabase login redirect lands on a Keycloak error page. Verify before deploying: `curl -I ${PUBLIC_KEYCLOAK_URL}/realms/${PUBLIC_KEYCLOAK_REALM}/.well-known/openid-configuration` must return 200.

 - Check `MAX_REPLICATION_SLOTS` in PostgreSQL and `REALTIME_MAX_CONNECTIONS` before going to production.

+  Fase 17.2 — About-modal that renders the repo-root CHANGELOG.md.
+
+  Architecture notes:
+    * CHANGELOG is imported via Vite's `?raw` query so the file is
+      bundled at build time — no fetch at runtime, no SSR + adapter-node
+      filesystem read, no service-worker miss. Bundle size is ~6 KB
+      today; revisit (dynamic import, marked, etc.) when it grows past
+      ~30 KB or starts using non-trivial markdown features (tables,
+      links, code blocks).
+    * The path is 5 levels up from this file:
+      components → lib → src → web → apps → repo-root. The plan
+      estimated 3; documenting the off-by-two so anyone moving the
+      component up/down the tree adjusts the import accordingly.
+    * Markdown is parsed inline (`renderMarkdown` below). Input is
+      static repo content, never user-supplied, so we're not exposed to
+      the usual sanitisation concerns — we still HTML-escape every
+      input line before adding our own tags to keep the surface clean
+      and to defend against accidentally putting `<` in a future entry.
+    * Esc + overlay-click both call `onClose`. We attach the keydown
+      listener to `window` only while the modal is open; otherwise
+      typing Escape outside the modal would still call back.

+	Fase 19.2 — Emoji picker.
+
+	Tabbed grid of ~280–360 emoji codepoints (see $lib/data/emoji-catalog).
+	Header is a tablist with 4 category buttons; body is a single grid for
+	the currently-selected tab. Switching tabs unmounts the previous grid
+	and mounts the new one — lazy-render — so the DOM never holds more
+	than `EMOJI_CATALOG[activeCategory].length` cells at once (the
+	"objects" tab is the smallest; "animals" is the worst case at ~140).
+
+	Props:
+	- `selected`: the currently-active emoji string (highlights the
+	  matching cell, if any).
+	- `onSelect(emoji)`: fired on cell click. Caller owns the persistence
+	  side-effect (update DB / Supabase row).
+
+	Keyboard nav: arrow keys move focus between cells in the active grid.
+	Cells are `tabindex={index === 0 ? 0 : -1}` (roving focus) per WAI-ARIA
+	grid pattern — the parent tab order has a single entry into the grid,
+	and arrow keys then walk it cell-by-cell. Tab order is consistent with
+	existing modals on the host pages (settings, onboarding, manage,
+	CreateCollectiveModal).

+/**
+ * Fase 19.1 — Emoji catalogue.
+ *
+ * Source of truth for the avatar / collective-icon picker. Hardcoded — not
+ * fetched — because the list grows once per Unicode release and is small
+ * enough (~280 strings, ~3KB) to ship in the JS bundle.
+ *
+ * Inclusion rules (kept narrow so every codepoint renders consistently on
+ * iOS Safari ≥ 16, Android Chrome, and desktop browsers):
+ *
+ *   1. Unicode 14 baseline only. Unicode 15 + 16 codepoints (🩷, 🩵, 🪿,
+ *      🪿, 🫨 etc.) are excluded — iOS < 17 renders them as tofu.
+ *   2. NO ZWJ sequences (no 👨‍👩‍👧, no 🐕‍🦺, no 🏳️‍🌈). Two reasons:
+ *      (a) the picker stores `users.avatar_emoji` as text and ZWJ
+ *      sequences serialize as multi-codepoint strings whose width is
+ *      font-dependent; (b) older Android skins render them as the
+ *      component glyphs side-by-side.
+ *   3. NO skin-tone variants (🏻 .. 🏿). Parked for a future pass — the
+ *      base codepoint always renders and is good enough for an avatar.
+ *   4. Variation selectors kept where the canonical emoji form needs
+ *      them (☀️ U+2600 U+FE0F, ❤️ U+2764 U+FE0F) — leaving them off
+ *      shows the text presentation.
+ *
+ * Total ~280 entries split across four categories. The catalog must satisfy
+ * the invariants enforced by `emoji-catalog.test.ts` (size lower bounds,
+ * no intra-category duplicates, no cross-category overlap).
+ *
+ * Mutation procedure when Unicode lifts the floor: edit this file by hand,
+ * run `pnpm --filter @colectivo/web test:unit -- emoji-catalog`, and verify
+ * the bundle-size delta stays under ~10 KB gzipped.

+	 * user. Each row pairs the local + remote JSON payloads side-by-side
+	 * and exposes two dismiss actions:
+	 *
+	 *   - "Discard local"  → accept the remote_won outcome (no-op
+	 *                        server-side: the remote version already won).
+	 *                        Hides the row from view via a localStorage
+	 *                        dismissed-set so the user sees a clean log.
+	 *   - "Discard remote" → same hide-from-view semantics but recorded
+	 *                        separately for analytics. The MVP does NOT
+	 *                        re-apply the local payload to the entity —
+	 *                        last-write-wins is permanent at the data
+	 *                        layer (see plan §14.scope: "no CRDT").
+	 *
+	 * Why localStorage and not a DB UPDATE: migration 016 marks
+	 * sync_conflicts as append-only at the RLS layer (no UPDATE/DELETE
+	 * policies). Fase 14 carries no DB migration. Dismissal is per-device,

+ *   EU-02 — Eva (no collective) lands on /onboarding with an
