/* =====================================================================
   Mobile-first responsive foundation + per-template layout
   Story US-002 — fluid layouts for every template the theme owns.

   Breakpoints:  mobile < 768px  |  tablet 768–1023px  |  desktop >= 1024px
   Strategy:     single-column stacked by default; grids/columns are added
                 progressively at >=768px and >=1024px. Nothing here styles
                 #primary by width, so self-contained templates such as
                 .gallery-page keep their own full-bleed layout untouched.
   ===================================================================== */
