Each day now has a full-height track behind a solid accent fill, so low-usage
days no longer render as a near-invisible sliver that only stood out on hover.
Feed, VideoCard, Sidebar, PlayerModal, Channels, Stats, SettingsPanel,
OnboardingWizard, NotificationCenter, Toaster, ErrorBoundary and the relativeTime
helper are now fully translated in Hungarian, English and German, each with its own
locale area file (auto-loaded). Key parity verified across all three languages.
Track who burned how much YouTube API quota. A QuotaEvent audit log (migration
0009) records every spend with the triggering user (NULL = background/system) and
an action label, set via a request/job-scoped contextvar (quota.attribute) so no
call signatures change. User-initiated work (sync subscriptions, unsubscribe,
opt-in recent backfill, manual enrich) attributes to the user; scheduler work to
System, split by action.
- backend: QuotaEvent model + migration 0009; quota.attribute() contextvar;
record_usage logs events; entry points wrapped (routes/sync, routes/channels,
scheduler); GET /api/quota/my-usage + GET /api/quota/admin
- frontend: admin-only Stats page (header nav, page=stats) with daily bars +
per-user breakdown by action and range picker; 'Your API usage' in Settings ->
Sync for every user
Verified: attribution + endpoints compute correctly; events are per-user vs System.
