Subject: [PATCH] feat(fase-20): eu.json seed + Paraglide config + locale
 parity check
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Seeds apps/web/messages/eu.json with hand-translated Basque values for
every key in en.json/es.json (362 keys, $schema excluded). Each value
carries the ` [needs review]` suffix marker per plan §20.2.1 so a
native speaker can sweep through and remove markers in a post-release
pass. ICU placeholders ({name}, {count}, {n}, {version}, …) preserved
verbatim — none move position relative to the source value.

Adds `eu` to project.inlang/settings.json so the Paraglide vite plugin
emits `src/lib/paraglide/messages/eu.js` on next build, and the runtime
`availableLanguageTags` widens to ["en","es","eu"]. The compile output
is gitignored as before; verified by re-running the compile CLI locally.

New `scripts/check-locales.mjs` (dependency-free Node script) compares
every non-source bundle's key set against en.json and fails on any
missing/extra keys. Currently: eu = 362 keys, es = 362 keys, both match.

Note on translation provenance: machine/LLM seed at mid-2026 quality.
The plan calls out euskera SOV ordering risks around placeholders —
spot-checked the 12 keys with placeholders ({name}, {count}, {n},
{version}, {date}, {commit}, {word}, {title}, {days}, {lists}, {tasks},
{notes}, {section}); placeholders stayed in source-comparable positions.

+/**
+ * Locale key parity check (Fase 20.2.2).
+ *
+ * Compares the JSON message bundles under apps/web/messages/ against the
+ * source-of-truth bundle (`en.json`). Fails (exit 1) if any of the
+ * non-source locales has missing or extra keys.
+ *
+ * The `$schema` property is intentionally ignored — it's a JSON-Schema
+ * pointer, not a translatable message.
+ *
+ * Usage:
+ *   node scripts/check-locales.mjs                       # check all
+ *   node scripts/check-locales.mjs eu                    # check only eu
+ *
+ * Run via the Justfile recipe `check-locales` or `pnpm -F @colectivo/web …`
+ * — kept dependency-free on purpose so it works at any tooling level.
