Subject: [PATCH] test(daycycle): #582/#544 witnesses follow the bounded,
 hint-free layers

smoke_live_pan_coverage now expects an exposed scene to open only within
clip-path: inset(-25%) and the clip-marked day-cycle outline never to open;
idle scenes keep no clip-path. paper-scene-contract pins the opacity hint.

The Release trailer asks the branch's push Validate for the heavy jobs
(smokes, golden, performance): #689 moves golden frames and must be proven
by the full smoke set before S7 (#690).

Release: v1.78.0-beta.9
Issue: #689
User-Visible: no
