/* Hotel web rack — «کاشی» (Persian hospitality). RTL, light/dark via light-dark() and color-scheme
   (system by default; [data-theme] forces one). Colour never carries meaning alone: statuses also have an
   icon/label, unconfirmed reservations a dashed edge, blocks and repairs a hatch.
   Performance: grid lines are a background image; only bars, bands, strip items and free-night rates are
   DOM nodes; no content-visibility on rows (measured: slower); no per-cell animation. */
