thejayman77 d13811319d zen: Phase B — UB swims with a behavior engine (wander, cruise/rest/burst, U-turns) ...

UB is no longer a static in-place loop. New behavior.js owns locomotion: UB wanders a
bounded tank, cruises at a chosen speed, drifts to new depths (nose tilts into it),
occasionally rests or darts, and banks through smooth U-turns at the edges — the tail
beats faster/slower with speed. All clips are in-place, so the engine drives world
position + heading and crossfades between the named clips (idle/cruise/burst/turnL/turnR).

Multi-clip GLB built via tools/glb-split/build-clips.mjs (5 clips, 8.7MB — orphaned Take
accessors explicitly disposed). aquarium.js reworked: clip crossfade + per-frame behavior
apply. Tuner (/zen?debug=1) now exposes scale + Behavior (cruise speed / roam width /
roam height / liveliness) + the fins section. Reduced-motion calms speed + liveliness.
Still admin-gated.
