/**
 * Keyboard and assistive-technology adjustment for the knob.
 *
 * The surface already advertises `accessibilityRole="adjustable"` and takes focus, so this
 * is what makes that promise true: arrows nudge by `step`, shift makes them coarse, page
 * keys cross a tenth of the range, and Home/End pin to the bounds. Every keypress commits
 * (`final: true`) because there is no gesture to end.
 *
 * Physical keys are web-only, mirroring the rest of the library; on native the same moves
 * are exposed as increment/decrement accessibility actions, which is how VoiceOver and
 * TalkBack drive an adjustable control.
