- components/plan/PlanChangeSheet.tsx — upgrade/downgrade briefing per pricing-tiers.md §4
(fetches GET /api/plan/change-preview; gains/keeps/changes; recovery-safety line;
billing hint w/o purchase button; CTA row, no 'are you sure?' interstitial)
- debug.tsx: PlanOverrideToggle routes every flip through PlanChangeSheet first
- devices.tsx + protectedDevices.ts: 'degraded' status (red, inline 'protection expired —
remove the profile yourself' hint, no green checkmark); maxProtectedDevices limit hint
- mail.tsx + MailAccountCard.tsx + useMailStatus.ts: over-limit banner + paused-account
greyed-out + PausedBadge (all defensive — only shows if backend sends the field)
- blocker.tsx: free-tier transparency hint ('Grundschutz aktiv — voller Schutz: Pro/Legend')
+ custom-domain over-limit banner
- locales: plan.change.* + plan_limit.* (de + en)
tsc clean. Backend side (GET /api/plan/change-preview, paused/degraded fields) in progress
in parallel — UI built defensively to work before it lands.
