   TinySpacer — featured-categories.css
   -----------------------------------------------------------------------------
   Layout + card styling for the homepage "Browse by Room" section
   (template-parts/home/featured-categories.php).

   Scope: this file styles ONLY .ts-featured-cats and its .ts-room-card grid.
   It composes with global.css tokens and the .ts-section-heading component —
   it never redefines a shared component.

   Mobile-first. Min-width media queries only. No framework.

   Contents:
     1. Section shell
     2. Responsive grid
     3. Room card (media, body, arrow cue)
     4. Interaction (hover / focus-within / stretched link)
     5. Reduced-motion & forced-colors

   2. RESPONSIVE GRID
   -----------------------------------------------------------------------------
   1 column (mobile) → 2 columns (>=40em) → 3 columns (>=64em).
   Built locally rather than via .ts-grid--cols-3 so the card wall reads as a
   semantic <ul> list with its own reset.

   3. ROOM CARD
   -----------------------------------------------------------------------------
   Whole card is clickable via the stretched-link pattern: the <a> inside the
   title projects a pseudo-element over the entire card, so the card is a single
   pointer target while remaining one accessible tab stop.
