# Landing rework — join flow, player rosters, account, mod list, footer

> **Status: PLANNED — not started.** Five landing workstreams (WS1–WS5) plus the
> mod-list component from `17-mod-shortlist.md` (WS6). Each is independent; suggested
> order: **WS5 → WS1 → WS2/3 → WS4 → WS6** (trivial first; rosters share avatar
> plumbing; account reuses register's skin JS; mods last).

The landing is an **Astro static site** (`landing/`, pnpm, output → `../www/`), built
on the host with `.env` sourced. Three locales (en/es/eu) in `i18n/ui.ts`, identical
shape; non-translatable config in `data/site.ts`. Runtime data (status, rosters, Drasl
API) is fetched client-side; everything else is SSG.

## New env keys (`.env` + `.env.example`)

| Key | Consumer | Purpose |
|---|---|---|
| `AVATAR_MODE` (default `headiso`) | landing build → `site.ts` | NMSR render mode for avatar tiles |
| `DRASL_ADMIN_USERNAME` / `DRASL_ADMIN_PASSWORD` | **mc-status** (compose env) | admin login for the registered-players roster — **never** reaches the browser |

Use a **dedicated, rotatable** Drasl admin account for these creds (Drasl has no
read-only role; full-admin, but isolates blast radius from your personal admin).

## WS1 — Join flow off packwiz (homepage = UlicraftLauncher, 3 steps)

The modpack now ships via **UlicraftLauncher** (rebranded HeliosLauncher in the
`custom-launcher` repo) — it installs mods (packwiz), auth (Drasl, preconfigured) and
all files itself. So the homepage join flow drops the packwiz step and the manual
authlib step.

**Homepage steps (3):**
1. **Register** — create your Ulicraft account (link `/register`).
2. **Download the Ulicraft Launcher** — per-OS download (from manifest); log in with
   your credentials. (No authlib URL — launcher is preconfigured.)
3. **Join the server** — launch, connect to `site.serverAddress` (IP copy chip).

**Launcher manifest (delivery = synced local file, option B):**
- Contract: `landing/src/data/launcher-manifest.schema.json` (already written;
  JSON-Schema draft 2020-12).
- The `custom-launcher` release flow **produces** `launcher-manifest.json` and syncs
  it into `landing/src/data/launcher-manifest.json` (gitignored, generated), same
  pattern as `sync-server-mods.sh`.
- Landing **imports** it at build → renders per-OS buttons from `builds[]`. Missing
  file → hide the buttons (build must not fail).

**Fjord — alternative path, OWN page, off the homepage:** new `/fjord` (+ `/es`,
`/eu`). Download Fjord (existing `/launcher/` mirror), add authlib-injector account
(`site.authlibUrl` chip), import `manifest.fjordPack` (`.mrpack`), connect.

Tasks:
- [ ] `site.ts`: delete `packwizUrl`; replace `launcher` (Fjord hardcode) with the
      manifest import; rename product display to "Ulicraft Launcher".
- [ ] `ui.ts`: rewrite `join` block (3 steps) in **all three** locales; eyebrow "3
      Steps"; reword the `features` item that name-drops packwiz.
- [ ] `[...lang].astro`: collapse the 4-step join markup → 3; remove packwiz `CopyChip`,
      keep server-IP chip; render download buttons from manifest.
- [ ] New `[...lang]/fjord.astro` + `ui.ts` `fjord` block + `LANG_FJORD_PATH`.
- [ ] Document the synced-manifest step in `12-build-order.md` / `14-deploy.md`.

## WS2 — Live server status: online players with names + 3D avatars

`ServerCard.astro` already fetches mc-status (`/api/mcstatus/v2/status/java/${BASE_DOMAIN}`,
mcstatus.io v2 JSON: `players.online/max/list[{uuid,name_clean}]`) and renders NMSR
`headiso` heads (filters the zero-UUID placeholder). Enhancement: labeled avatar tiles
(name + avatar) using `site.avatarMode`.

Tasks:
- [ ] `ServerCard.astro`: per online player render a **shared avatar tile** (name +
      `${avatarUrl}/${avatarMode}/<uuid>?size=N`). Keep count + fill bar.
- [ ] `main.css`: `.roster`/tile styles (shared with WS3).

---

## WS3 — Registered players roster (live, via mc-status)

`GET /drasl/api/v2/players` (list all) is **admin-only** → cannot be a browser fetch.
Serve it **live** through mc-status (the trusted internal proxy that already emits
sanitized public JSON). **Coupling accepted** (4–10 friend server) with two mitigations:
isolate the roster fetch (own timeout + cache; the status path never blocks on Drasl),
and use a dedicated rotatable admin account.

mc-status (`docker/mc-status/main.go`) gains a `/players` endpoint:
- On request (cache TTL ~60s): if no cached token, `POST http://drasl:25585/drasl/api/v2/login`
  with admin creds → cache `apiToken` (re-login on 401). `GET …/players` (Bearer) →
  map to `[{uuid,name}]` → cache → serve JSON, CORS `*` (like the status route).
- Caddy already `handle /api/mcstatus/*` → mc-status, so the public path is
  `/api/mcstatus/players` (browser fetches **same-origin**, no CORS, no admin token in
  the page).

`PlayerRoster.astro` (new) fetches `/api/mcstatus/players` client-side → live grid of
shared avatar tiles. Roster is **public** (uuid+name) — accepted.

Tasks:
- [ ] `main.go`: `/players` handler (Drasl login + list, token cache, TTL cache,
      isolated from the status path).
- [ ] `docker-compose.yml`: pass `DRASL_ADMIN_*` env to mc-status.
- [ ] New `PlayerRoster.astro` + a "Members" section in `[...lang].astro` + `ui.ts`
      keys (3 langs).

## WS4 — Player account page (skin CRUD)

New `/account` (+ `/es`, `/eu`), browser-direct Drasl (proven by `/register`; CORS
already scoped to the apex). **Skins only** (capes out). One player per user
(`players[0]`, no switcher). Token **in-memory only** (refresh = re-login; no
localStorage → no XSS token theft).

- **Read:** `POST /login {username,password}` → `{apiToken, user.players[0]{uuid,name,skinUrl}}`.
- **Create/Update:** `PATCH /players/{uuid} {skinBase64, skinModel}` (Bearer).
- **Delete:** `PATCH /players/{uuid} {deleteSkin:true}` → reverts to default.

UI: login form → reveal skin panel (current avatar via NMSR `site.avatarMode`, model
radio classic/slim, file picker, [Upload], [Reset to default]). After upload, NMSR lags
~15m → show the **just-picked file** locally (FileReader dataURL) as instant
confirmation, not a fresh NMSR render.

Tasks:
- [ ] New `[...lang]/account.astro` — lift skin JS near-verbatim from
      `register.astro:250-307` (`readBase64`, PATCH, `apiMessage`).
- [ ] `ui.ts`: `account` block (reuse `register.skin*`) + `LANG_ACCOUNT_PATH`.
- [ ] `main.css`: reuse `.reg-*` tokens.
- [ ] `register.astro`: repoint the "Manage it here" footer link from the Drasl web UI
      to `/account`.

---

## WS5 — Footer status link

Add a link to `https://status.${BASE_DOMAIN}` in every footer. Nav unchanged.

Tasks:
- [ ] `site.ts`: add `statusUrl`.
- [ ] `ui.ts`: add `footer.status` (3 langs).
- [ ] Add `<a target="_blank" rel="noopener">` in `.footer-links` of `[...lang].astro`,
      `register.astro`, and the new `account.astro` / `fjord.astro` footers.

---

## WS6 — Mod-list component (auto-generated, see `17-mod-shortlist.md`)

Shows the **installed pack** (full client set from the distribution forgemods), flat
alphabetical, pretty names + extracted logos, no categories, no external links.
Build-time baked.

New `tooling/build-modlist.py` (mirrors `classify-mods.py`: `tomllib` + `zipfile`,
offline) reads `$DISTRIBUTION_WEB_ROOT/servers/ulicraft-1.21.1/forgemods/required/*.jar`:
- Per jar: parse `neoforge.mods.toml`, take the primary `[[mods]]` → `displayName`
  (fallback modId), `version`, `description`, `authors`; extract `logoFile` PNG → write
  `landing/public/mod-logos/<modid>.png` (skip if absent → `logo: null`).
- Write `landing/src/data/mods.json` (gitignored, generated), sorted by `name`:

```json
{
  "schemaVersion": 1,
  "count": 76,
  "mods": [
    { "id": "jei", "name": "Just Enough Items (JEI)", "version": "19.27.0.340",
      "authors": "mezz", "description": "…", "logo": "/mod-logos/jei.png" }
  ]
}
```

`ModList.astro` (new) imports `mods.json` → flat grid (logo + name + version). The
homepage stat tile (`site.ts` `stats[0].key "50+"`) is fed from `mods.json.count`.

Tasks:
- [ ] `tooling/build-modlist.py` (jar parse + logo extract + `mods.json`).
- [ ] New `ModList.astro` + a "Mods" section in `[...lang].astro` + `ui.ts` heading
      keys (3 langs).
- [ ] `site.ts`: feed `stats[0]` count from `mods.json`.
- [ ] Run the generator pre-`pnpm build`; document in `12-build-order.md` /
      `14-deploy.md`. `.gitignore`: `landing/src/data/mods.json`,
      `landing/src/data/launcher-manifest.json`, `landing/src/data/players.json` (if
      any baked), `landing/public/mod-logos/`.

---

## Verification (whole rework)

- **Build:** `cd landing && set -a && . ../.env && set +a && pnpm run build` then
  `pnpm check`. Must pass offline even if `launcher-manifest.json` / `mods.json` are
  absent (buttons/list hidden).
- `grep -ri packwiz landing/` → no live join references remain (Fjord page may mention
  its own import).
- **Local preview** (`pnpm dev`): all three locales — 3-step join, online roster, members
  grid, account page, footer status link, mod grid, `/fjord` page.
- **Rosters (running stack):** online tiles appear with players on; `/api/mcstatus/players`
  returns `[{uuid,name}]`; the members grid renders avatars.
- **Account (running stack):** login → upload PNG → instant local preview → in-game/NMSR
  reflects after ~15m → reset reverts to default.
- Deploy via the `deploy` skill; the manifest sync, `build-modlist.py`, and landing
  rebuild are **host** steps (not compose) — fold into `14-deploy.md`.
