 * - `translate` feeds `panAccumulatedPixels` as a WORLD-space direction (input classes orient local
 *   intent into world space before populating it, mirroring the legacy `cameraDirection` surface).
 * - `rotate` feeds `rotationAccumulatedPixels` (x=pitch, y=yaw), mirroring legacy `cameraRotation`.
 *
 * These camera classes have no separate zoom channel: mouse-wheel input folds into translation/rotation
 * just like the legacy inputs, so there is no `zoom` interaction here.
 *
 * Input classes inject deltas using the same scaling they applied historically and the movement
 * system leaves all speed multipliers at 1, so at the reference framerate the per-frame applied
 * delta matches the legacy value exactly while inertial glide becomes framerate-independent.
