// Bare on/off switch: a track with a sliding knob and no label. This is the
// switch `Toggle` parks at the end of its labeled row, factored out so panel
// headers and other compact controls render the identical thing.
//
// The caller owns the value: bind `checked` to real state and flip it in
// response to `toggled()`. Services that already track a desired state
// optimistically (see the Tailscale service's `_desired`) get an instant knob
// throw for free, because `checked` is already the optimistic value.
//
// `busy` marks an operation in flight and swallows further clicks, but leaves
// hover, cursor, and tooltips alone so the control does not flicker every time
// a background refresh runs.
//
// The cursor is a ring drawn outside the track rather than a state on the
// track itself: themes give normal chrome a stronger border than hover-cursor
// (0.4 vs 0.25 by default), which is right for controls that are borderless at
// rest but would make a bordered track go *fainter* under the cursor. On the
// panel background the ring reads immediately. `cursorRing` follows
// `interactive` — a switch whose surrounding row owns the click owns the
// cursor too.
//
// `rounded` auto-detects from Style.cornerRadius so the switch follows the
// theme: pill shape when Hyprland corners are rounded, square on sharp.
