- First-visit language auto-detect (Spanish devices land in es; stored choice wins).
- Sasquatch AI replies in the app language (skate trick names kept English).
- i18n safety net: scripts/check-i18n.mjs wired into npm test — fails on any t()
key missing from en/es or any en/es key drift.
- ~1,680 new keys (2,297 total) across mapUi / spotUi / marketUi / labUi and
~65 files wired to t(): Map, spots (detail/create/edit/chat), marketplace,
trades, offers, escrow, shipping, The Lab, /become/* forms, coaches, skaters.
- Policy: only skate TRICK names stay English; user-generated content untouched.
