Camera architecture: a module with directCamera:true drives its own rig
inside update() (analytic f(timeline, seed, framing, venueState)); the
shared rig is ignored for that layer only. ModelLayer prefers own camera,
Show skips shared injection. Ride migrates its full grammar over
(traverse, orbit, car tracking, jumps, clamp); Compositor ride branches
removed. Chamber/stage unchanged on the shared path.
Sidewalk shot: new ride-only 'passerby' plan target (breaths only, never
climax, never twice running) plants a static roadside camera; the module
drives the car +12 to -14 on driveT with the world frozen. Verified
far-pass-away through the Show path; lint + 24 tests green.
