Tier 3: bubbles, animation, wrap mode, XYPad, AlphaDisplay, PushButton

- valueBubble/bubbleFormat: floating readout above knobs while dragging
  (Knob-based skins + ImageKnob)
- animateChanges: rAF ease-out tween of the pointer on programmatic
  value changes; user gestures snap; prefers-reduced-motion disables
- wrap: endless encoder mode — values and relative drags roll around
  min↔max; pairs with angleOffset={0} angleRange={360}
- XYPad: two-parameter pad with absolute drag, arrow keys (Shift
  coarse), Escape cancel, double-click reset, grid/crosshair, focus
  ring, hidden form inputs, change meta
- AlphaDisplay: fourteen-segment alphanumeric LED (A-Z, 0-9, symbols,
  decimal points, chars padding/align, glow/skew)
- PushButton: studio panel button with LED strip — toggle or momentary,
  controlled/uncontrolled, aria-pressed, hidden form input
- Docs: five new gallery cards incl. animated preset demo, API rows,

 - `wheelStep` / `wheelRequiresFocus` — tune wheel notches, or keep hover-scroll free.
 - `onChange` / `onChangeStart` / `onChangeEnd` — gesture-aware callbacks with
   `meta.source` (`'drag' | 'wheel' | 'keyboard' | 'reset' | 'api'`).
+- `wrap` — endless encoder mode: values roll around min↔max (pair with
+  `angleOffset={0} angleRange={360}`).
+- `animateChanges` — tween the pointer on programmatic changes (preset loads);
+  gestures never animate and `prefers-reduced-motion` is honored.
+- `valueBubble` — floating readout above the control while dragging.
 - `name` — hidden form input for plain `<form>` posts; every component forwards a
   ref to its root element, and SVG parts carry `data-part` attributes for CSS.
