- New Cloud Function: onEntitlementChanged (Firestore onWrite on entitlements/premium) — edge-triggered inactive→active, notifies the OTHER partner so couple-shared unlock isn't silent
- New notification type SUBSCRIPTION_CHANGED → routes to SUBSCRIPTION
- AnswerRevealViewModel: re-issue markRevealed if best-effort failed (offline/transient) so partner_opened_answer push eventually fires
- firestore.rules: harden users/{uid} update allowlist (defense-in-depth; no live hole)
- 18 new brand glyph vector drawables (drawable-nodpi/)
- SettingsScreen / PlayHubScreen / WaitingForPartnerScreen: swap Material icons for new brand glyphs
- ClaudeQA docs + Future.md updated
