+ * A slider whose displayed value is decoupled from its reactive source.
+ *
+ * Why this exists (#111): the player components run a 60fps requestAnimationFrame
+ * loop (progress clock, #107) that re-renders the whole component every ~16ms.
+ * Binding a range `<input :value>` straight to a reactive source (the store
+ * volume) let Vue re-apply `el.value = source` on every one of those re-renders.
+ * Mid-drag the source is still the *old* value, so the native drag position kept
+ * getting snapped back — the thumb was effectively un-draggable on desktop and
+ * janky on mobile.
+ *
+ * The fix is to bind `:value` to a LOCAL ref that:
+ *  - tracks the native drag synchronously via `@input` (so the bound value always
+ *    equals the element's value → Vue never resets it), and
+ *  - is committed to the real source only on `@change` (release).
+ * External source changes (bot switch, another client) still flow into the
+ * display — except while the user is actively dragging, where they must be
+ * ignored or they'd fight the drag.
+ *
+ * @param source  getter for the authoritative value (e.g. () => bot?.volume)
+ * @param commit  called with the final value on release (e.g. store.setVolume)
+ * @param fallback value to show when the source is undefined (default 75)
