"""The live sick day: tonight is raised to 20:00 plus the day's gaming pay.

Since earned_time 0.13.0 credits stack on 20:00 at gaming pay (kuhy,
2026-10-17: LeetCode + reading on a sick day is 22:00, not 20:10). The pass
raises to the derived target (``_sick_floor.sick_target``) and records no
lift, so nothing is absorbed.
