/* ==========================================================
   RESPONSIVE TIER: ULTRA-WIDE (2K / 4K, >= 2240px)
   The desktop composition is tuned for ~1920–2234px. Above that,
   full-bleed *content* bands would stretch text into unreadably long
   lines, so we cap the content-heavy containers at the top of the
   approved desktop range and center them. Image bands (hero, video,
   CTA photo) intentionally stay full-bleed. The 2240px floor sits just
   above the reviewed desktop width so nothing changes at <=2234px.
