/* ================================================================
   CONTENT GRID: UNIVERSAL LAYOUT (2026-07-02)
   One site-wide layout primitive. Named grid columns give every
   page the same width system:

     [full]    the 1344px (84rem) main content frame + gutters
     [wide]    84rem (1344px): tables, gate lists, cards, data
     [popout]  56rem: callouts that sit proud of the prose
     [content] 48rem: prose measure (default for all children)

   The grid itself is capped at the frame (owner directive
   2026-07-02): nothing bleeds past 1344px + gutters; the whole
   frame centers in the viewport. Mobile-first: the outer rails
   collapse to --grid-pad on small screens; the width system
   itself needs no media queries.

   Phase 1 (this block): .page-content is aliased onto the grid so
   all 10 reading pages inherit it with zero HTML changes. Marketing
   pages join in the sweep phase by replacing .section__shell with
   .content-grid > .wide.
