/* =========================================================================
   OLAM by Plasseril — ripple build
   Layout and interaction structure mirror the ERA Residence teardown:
   sticky-runway scroll (no GSAP pins), per-element theme swapping,
   CSS-var motion protocols, one ratio driving the display type scale.
   Written from scratch — none of ERA's stylesheet is reused.
   Palette and type per BRIEF.md §12. WCAG 2.1 AA is a hard requirement.
