/* ============================================================
   WORKING HOURS — Settings › Working Hours
   Markup is generated by public/js/working-hours.js.

   Layout note: the old pane put the weekly schedule into one column of a
   2-column `.form-grid` (auto-fit minmax(360px, 1fr)). At the common desktop
   width that column was ~270px wide while `.hours-row` asked for
   `200px 1fr 1fr` + 32px of gap — so the two time inputs wrapped on top of
   each other and the toggle in the third column was pushed past the card's
   `overflow: hidden` edge and clipped. Everything here uses `minmax(0, 1fr)`
   for flexible tracks (a bare `1fr` has an auto minimum and refuses to shrink
   below its content, which is what caused the overflow) and collapses to a
   single column before the row can get tight.
