speechSynthesis is silently muted on iOS Safari and Chrome Android after the audio session ends (onended), so chapter announcements never played. Fix: - Add GET /api/tts-announce backend endpoint: streams a short TTS clip for arbitrary text without MinIO caching (backend/internal/backend/) - Add GET /api/announce SvelteKit proxy route (no paywall) - Add announceNavigatePending/announcePendingSlug/announcePendingChapter to AudioStore - Rewrite onended announce branch: sets audioStore.audioUrl to the announcement clip URL so the persistent <audio> element plays it; the next onended detects announceNavigatePending and navigates - 10s safety timeout in case the clip fails to load/end
