   padding, fully-rounded. Off = white bg + #D5D7DA border, thumb

   darkens the On fill; Focus adds the shared focus-ring; Disabled uses
   flat #E9EAEB (off) / #CFE1FC (on) with no border.

   One live, fully-interactive control per sheet — no static "state
   copy" instances. Every state below is reachable by actually hovering,
   tabbing to, or clicking the control. `position: relative` on the
   label is required so the visually-hidden input lines up exactly over
   the visible track (without it, the input's hit target drifts and the
   control stops responding to clicks — this was the "broken toggle" /
   "checkbox not interactive" bug).
