/* ==========================================================
   01 Hero — the SeaBreeze plate that gets pulled into the page.

   How the effect works (mirrors pier88coast.com's hero):
   - The plate is position: fixed to the bottom of the viewport.
   - The hero is its own stacking context (isolation: isolate), so every
     section after it paints *over* the fixed plate.
   - A front wave sits above the plate, and js/hero.js pushes the plate
     down via --plate-exit-y as the hero scrolls away. The plate therefore
     looks like it is dragged down beneath the wave and into the page.
