- Range picker (?range=7d|30d|1y|all) drives every section; the hours chart
covers the whole range (daily for 7d/30d, weekly for 1y, monthly for all).
- Genres from Last.fm artist top tags (music.artist_tags, normalised and
filtered), split by artist listening time, with a per-bucket stacked chart.
- Listening clock, new artists, comparison with the previous period and top
movers, streaks, milestones, top albums with art, rank changes.
- music.play_facts materialized view (refreshed by the app when plays arrive)
plus a per-range cache keep the page fast.
- scripts/music-fetch-tags.ts backfills tags, most-played artists first.
