/* ============================================================
   ASCENDANCE — cinematic dark / luxe
   ------------------------------------------------------------
   Near-black canvas. One molten ember accent. High-contrast
   editorial serif (Fraunces) against a precise grotesk and
   technical mono. Filmic grain, volumetric light, and a
   hand-built motion language where scrolling reads as ascent.
   Dark is the default; a high-altitude "daybreak" light theme
   lives under [data-theme="light"].
