v2.3.0 (2026-09-06)

For night owls: the reading day can start when yours does.

• A configurable day start. Preferences gains a "Reading day" group:
  pick the minute past midnight your reading day begins (arrows step 30
  minutes, or type HH:MM; the default 00:00 is the plain calendar day).
  With a 04:00 day start, reading done between midnight and 04:00 counts
  toward the previous day, so one late-night sitting reads as one day
  everywhere a day appears: daily totals, streaks, the year heatmap,
  monthly bars, speed buckets, the 30/90/365-day windows, and every
  displayed date, including "today" in the streak rules. The change
  applies live. What never moves: the clock hours. The when-do-I-read
  heatmap still shows the real hour you read, and speed by hour and
  session starts stay on the clock.
