/* =============================================================
   ELEVATE MY DORM -- Rich Visual Treatments v1
   Layered ambient FX for headline styles. Stacks ON TOP of the
   base color-grade filters in presets.css. All overlays are
   pointer-events:none and clipped to the canvas, sitting above the
   room (z auto) + spatial layers (z5/6) but below the score pill (z40).
   Activated by a body-level class: body.fx-<style>.
