A rest day is earned: one for every seven kept days, a bank of two. A miss spends one automatically. It is never sold.
No evening at-risk state, no loss animation, no guilt copy. Absence creates no debt .
Read opens as normal, with no message. Progress explains it once: Tuesday was covered by a rest day. 1 rest day banked.
Shown once on Read, for 3 seconds, no button. The chip shows the outline flame and 0. The old run stays in Progress as history.
