     2.  Reset & base
     3.  Reusable utilities (.container, .eyebrow, .btn, .reveal)
     4.  Header + burger
     5.  Nav overlay
     6.  Hero
     7.  Stats
     8.  Section heads + capability cards
     9.  Solutions
     10. Featured carousel
     11. Vision + pillars
     12. Gallery grid
     13. Footer
     14. Responsive breakpoints (mobile-first → up)
     15. Reduced-motion & focus (accessibility)

   Method: MOBILE-FIRST. Base rules target small screens; `min-width` media
   queries at the bottom progressively enhance for tablet/desktop.

   12. GALLERY GRID
   Uniform 16:9 grid. Every tile is 16:9; a tile tagged `.gallery__item--big`
   spans a 2×2 block — which is ALSO 16:9 (2×16 : 2×9 = 16:9).

   HOW THE 16:9 CELL IS ACHIEVED
   The grid is full-bleed (spans the full viewport width). Each column is
   (100vw − gaps) ÷ columns wide, so we set the row height to that column
   width × 9/16. Result: a 1×1 tile is exactly 16:9, and a 2×2 tile is ~16:9
   (off only by the thin gap). Column count is a fixed whole number per
   breakpoint, so the grid always fills the width and never cuts a cell.

   TO MAKE A TILE BIG: add the class `gallery__item--big` (2×2 block).
   That is the only size modifier — every other tile is a single 16:9 cell.
   `grid-auto-flow: dense` back-fills the gaps a big tile leaves behind, so a
   big tile that won't fit at the right edge simply moves down and the small
   tiles flow around it (same packing you see in the sample image).
