Counterpart to RunicGateway/website#77. - BACKEND_DESIGN.md: /public table now documents the new GET /public/version (DB-free identity/version), the version block on /public/status, and the brand block on /public/settings (per-shard theming: name/accent/logo/hero/favicon). - android/PLAN.md: mark §8 item 4 (version/health) and item 6 (branding) DONE and update the prerequisite-progress summary — all v1 prerequisites are now done; only push notifications (item 3) remains and is post-v1 (M7). App M0–M4 unblocked. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01NgyHnrNa8WwG3doxvxjuCr
