README + USER-GUIDE describe the sidebar picker and current coverage (home + shared chrome, per-tool bodies pending). DEVELOPER gains a how-to for adding packs and keys with the parity-test guarantee. TECHNICAL §10b records the in-house-JSON architecture and locks in the no-gettext decision (also logged in DECISIONS). REQUIREMENTS reflects the new interface surface and updated test count. COPY.md adds a "Language claim" slot so landing/email work can pick it up. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
