 * Controls the Reaper arrange-view scroll position and zoom level.
 *
 * Two styles of command are available for each axis:
 * - **Boolean (held)**: `startScrollLeft()` / `stopScrollLeft()`, `startZoomInX()` / `stopZoomInX()`
 *   etc. — models a held button. Scrolling/zooming continues while active and stops when
 *   released, matching the behaviour of hardware controller buttons. Mirrors how
 *   {@link Transport.startRewinding} works.
 * - **Rotary**: `scrollX(value)` / `zoomX(value)` etc. — sends a single relative step to
 *   a rotary encoder address. Positive values move right/down/zoom-in; negative values move
 *   left/up/zoom-out. Larger magnitudes scroll/zoom further per message.
 *
 * Reaper does not send feedback for any scroll or zoom command, so these are fire-and-forget.
