hectorqinandClaude Opus 5.5 3b1f8b46dc feat: 时长统计 — reading, watching and listening time by day, month, year and work
Reading time is counted by the reader: only while the page is visible and the
reader has turned, scrolled or tapped within three minutes, or while 朗读 plays.
It is kept per book per 15-minute UTC slot and per device install, saved
locally until sent, and stored as MAX(stored, reported) in the new
reading_time table, so a replayed report never counts twice.

Media time is derived on the server from the progress saves the web player and
Android Media3 already send: the smaller of the wall-clock gap and the position
advance between two saves of one session, gaps over 30s ignored. It is stored
in media.db (media_watch_time), so neither client changes.

我的 → 时长统计 shows a stacked bar per day (one month), month (one year) or
year, with a legend that filters by kind, a table view and the works ranked for
the range or the bar picked. Administrators also get every account's totals.
Chart colours are new mode-level tokens (--color-chart-1..4), validated for
colour-vision separation on both surfaces. The React UI review now covers the
page and names the overflowing elements when a screen overflows.
