From LADDER_FROM (2026-10-10) shutdown is read down from sleep: ceiling =
WAKE_MINUTES (07:00) - 8h = 23:00, floor = ceiling - every earner's rung
(workout 110, LeetCode 50, reading 30, Anki 25, Automation 25) = 19:00.
A second workout earns nothing more. Earlier days resolve exactly as in
0.3.0 (frozen 23:00 ceiling); gaming is unchanged for every input.
WORKOUT gets a signed ledger (~/.local/share/workout_locker/ledger.json,
written by screen-locker) and workout_match; a rest_day row counts only if
declared before its day began. New API: first_credit_at, credit_units,
day_window, shutdown_minutes_for, extra_shutdown_minutes_for,
shutdown_ceiling_for, on_ladder, LADDER/Rung, LADDER_FROM, WAKE_MINUTES.
