/* Two-column "main + side panel" layout used by reception, booking wizard, etc. Collapses to a
   single column on tablet/mobile so the side panel never gets squeezed unreadably narrow.
   minmax(0, ...) tracks, not bare fr units: a grid item's automatic minimum width defaults to its
   content's min-content size, so any wide unwrapped content nested inside (e.g. the booking
   wizard's horizontally-scrollable day-picker strip) blows the whole track — and this page — out
   past the viewport on mobile, even though that inner content has its own overflow-x:auto. Found
   via a real-browser mobile QA pass; no DOM-only test catches a grid sizing bug like this. */
