Epic 2.5.1: basis for framing layer

 independence (§1 of PLAN.md) and with the feedback buffer, and the four items above will have
 changed what it needs to do.
 
+**Status after the first pass: shipped, deliberately simple.**
+
+A shot now carries a size and a recentre, applied inside `sigCamera` in scene coordinates —
+rendered close rather than magnified, which is what keeps it resolution-independent and free at
+4K. `look/framing.js` owns the vocabulary: three shot sizes with measured headroom (a close-up
+past ~2.2 is a blurry wide, a wide past ~0.55 is a speck), and a per-track style (`locked` /
+`gentle` / `edited`) that decides how far sizes travel and how often a cut also changes the shot.
+The arc driver plans one framing per cue, walking the cuts in order so the whole video gets a
+consistent hand and a seek finds the same framing as playback. The gates hold it honest: cuts
+actually change size, sizes stay in headroom, and two drivers over one look agree on every shot.
+
+What this pass does not do, and the reason it is "simple": the framing is constant within a shot.
+A zoom that moves during a shot is a separate device and would fight the drift LFO and the slow
+axis, both of which already own continuous motion. Scenes built outside the shader contract (the
+single 3D layer) are not framed yet. Both are the obvious next steps and neither is required for
+a working project.
