v1.1.3: Radix-composable buttons, meter ballistics/dBFS/loudness, PanKnob

- PushButton/Button forward native button props (...rest) and compose their
  own event handlers with consumer/Radix-injected ones, so a Button works as
  a Radix `asChild` trigger (dropdowns/tooltips/popovers). Prop types now
  extend React.ButtonHTMLAttributes.
- Meter gains opt-in metering: `ballistics` (PPM attack/decay), `peakDecay`
  (peak-hold fall tail), `scale="db"` (feed amplitude → dBFS with reference
  lines; min/max default -60/0), and `integrated` (windowed LUFS-ish loudness
  readout + marker). New rAF engine in meterEngine.ts with ampToDb/dbToAmp
  helpers; default behavior unchanged.
- New `PanKnob` — bipolar stereo pan: fills from center, center detent,
  L<n>/C/R<n> readout, -50..50 default.
- Docs: ApiDocs rows + recipes (dBFS meter, pan strip, Button-as-trigger),
  gallery cards (dBFS meter, Pan) + a Regenerate Button in the panel.
  CHANGELOG 1.1.3; version 1.1.3; install URLs bumped.

Library + docs typecheck and build; 46 tests pass.

- Meter dBFS readout: muted-grey unit labels (LUFS matched to dB), value-first
  layout in an aligned 2-column grid so peak/loudness decimals line up, and
  ghost pad digits removed — the loudness row no longer looks like a stray tag.

- Action buttons (Button / PushButton mode="action") no longer show an LED
  by default — an action has no state to indicate. led defaults to 'strip' for
  toggle/momentary and false for action; led="dot"/"strip" opts back in.
- Meter dBFS readout: units (dB / LUFS) sit centered directly under each
  value; grid alignment tidied and ghost pad digits removed. Docs: dBFS-meter
  card moved next to the Meters card (same component) + a horizontal example.

 # Changelog
 
+## 1.1.3 — 2026-07-14
+
+Fourth integration-feedback release — a composability fix for buttons, a much
+smarter meter, and the pan control the mixer was missing.
+
+### Buttons
+- **Action buttons no longer show an LED by default.** `Button` (and
+  `PushButton mode="action"`) are plain by default — an action has no state to
+  indicate. `led` defaults to `'strip'` for `toggle`/`momentary` (which do have
+  a state) and to `false` for `action`; pass `led="dot"` / `led="strip"` to opt
+  a command button back in.
+
+### Buttons compose as Radix triggers
+- `PushButton` / `Button` now forward unknown props (`...rest`) to the
+  underlying `<button>` and **compose** their own event handlers with any the
+  consumer (or a Radix `asChild` slot) injects. A `Button` can now be a
+  dropdown / tooltip / popover trigger: `onPointerDown`, `onKeyDown`,
+  `data-state`, `aria-expanded` etc. all reach the DOM and fire alongside the
+  button's own press behavior. The prop types now extend the native button
+  attributes.
+
+### Meter — ballistics, dBFS, loudness
+- **`ballistics`** — PPM-style attack/decay smoothing of the displayed level
+  (`true` ≈ 5 ms attack / 350 ms decay, or `{ attack, decay }` in ms).
+- **`peakDecay`** — the peak-hold marker falls with a decay tail (normalized
+  units/second) after `peakHold` instead of snapping back.
+- **`scale="db"`** — feed linear amplitude (0..1) and the meter displays dBFS;
+  `min`/`max` default to -60 / 0 dB and faint reference gridlines are drawn
+  (`showScale` / `referenceTicks` to tune). New `ampToDb` / `dbToAmp` helpers.
+- **`integrated`** — a time-windowed loudness estimate (LUFS-ish on the dB
+  scale — a windowed mean of channel power, not a full BS.1770 measurement),
+  shown as a secondary readout and a marker line (`integrationWindow`,
+  `loudnessColor`).
+- All of the above are opt-in; the default meter behaves exactly as before.
+
+### New component
+- **`PanKnob`** — a bipolar stereo-pan knob: fills from center, snaps to a
+  center detent, reads out `L<n>` / `C` / `R<n>`. Defaults to a −50…50 range
+  centered at 0.
