   Progressive enhancement contract
   --------------------------------------------------------------------------
   Base rules (no ancestor class needed) render every section as plain,
   fully-visible stacked content — the correct behaviour with JS disabled.
   The `.js:not(.reduced-motion)` ancestor (set by an inline <head> script,
   see index.html) unlocks the pinned / absolutely-positioned / 3D layouts
   that main.js then animates with GSAP. `prefers-reduced-motion` is also
   honoured natively via @media so it works even before JS runs.
