/* Your Flow kit v1, kit-controls.css (lane A): buttons, fields, chips, option
   rows, the stepper, tabs, links and the sheet. Ported from the approved
   prototype's flow.css. Every colour is a token from kit.css, and only
   transform and opacity move: a control answers a press with a small scale,
   and a colour change is instant. Selected states are drawn off aria-pressed,
   aria-selected, :has(input:checked) and a plain .is-selected, so whichever
   the control sets, the visual follows. */
