- Mini player shows as soon as generation starts (not just when audio ready)
- Idempotency: tapping headphones again during generation is a no-op
- Playback resets to position 0 on completion (standard player behavior)
- Stop button in full player visible during generation
- PodcastLibraryView lists all generated podcasts
- Sparkles menu gains Podcasts entry
- Fix AnalyticsService Sendable error (serialize before Task.detached boundary)
AnalyticsService.track() is fire-and-forget — posts to POST /v1/marks/events
which records a Langfuse trace. No external SDK, no Sentry on iOS side.
Events tracked:
- podcast.started (url, cached)
- podcast.completed (url, durationSec) — fires at 97% playback
- podcast.failed (url, error)
- search.semantic (query, resultCount)
- enrich.completed (count)
- collections.generated (collectionCount)
