Three review findings on the per-panel camera work:
- highway_3d: _bgPanelKey() resolved splitscreen via window.feedBackSplitscreen
only, while _freeCamFor() uses the feedBackSplitscreen||slopsmithSplitscreen
alias it claims to "mirror". If the rename lands, per-panel background settings
would silently stop being per-panel while the camera stayed per-panel. Resolve
the alias the same way in _bgPanelKey.
- drum_highway_3d: applyCamera()'s "before first positionCamera()" guard tested
`_camBaseH == null`, but _camBaseH/_camBaseD were initialized to 0, so the guard
never fired (and could apply a base-0 pose for a frame). Initialize to null.
- keys + drum: the PR claimed the Camera Director resolver was unit-checked, but
nothing exercised it. Extract the resolver into pure, exported helpers
(_resolveFreeCam + _ssApi), delegate the per-instance _freeCamFor to them, and
add tests/camera_bridge.test.js covering per-panel select, global fallback,
null-when-absent, throw-safety, and the slopsmith-alias resolution. Drum 15→21,
keys 50→56, all pass; behavior unchanged.
