/* ---- Drawer product row: 3-position sliding toggle ---- */

/*
 * Mirrors the 2-state .toggle-track / .toggle-thumb pattern from inputs.css.
 *
 * Three data-state values on .slot-toggle:
 *   "am"   — thumb slides to the left  (AM position)
 *   "none" — thumb rests in the centre (default, nothing submitted)
 *   "pm"   — thumb slides to the right (PM position)
 *
 * Sizing derived from the 2-state toggle:
 *   Track height  : 1.5rem  (identical)
 *   Thumb diameter: 1.125rem (identical)
 *   Inset         : 3px     (identical)
 *   Track width   : 5rem    (widened to fit 3 equidistant stops)
 *
 * Travel per step = (5rem - 2×3px - 1.125rem) / 2 ≈ 1.75rem
 *   AM   → translateX(0)
 *   none → translateX(1.75rem)
 *   PM   → translateX(3.5rem)
 *
 * Colour language:
 *   AM   — mint         (matches the form's primary active colour)
 *   PM   — lighterGrape (muted mauve-lavender; reads "evening/dusk" without
 *                        veering into warm-red alarm territory)
 *   none — darkerGrape  (inactive, same as 2-state off state)
