/* ---------- Keynote hero (flagship project treatment) ----------
   A pinned scrollytelling centerpiece (see js/scroll-centerpiece.js): this
   section fills the viewport, GSAP ScrollTrigger pins it while the WebGL
   wafer scene behind the content plays its zoom, then releases into normal
   scroll. Content is an overlay over a full-bleed canvas layer, not a
   side-by-side grid column — the "animation plays in the back, heading
   stays put" structure is literal here, not simulated with CSS transforms
   (the old per-element --sp scroll-linked tilt/brightness filter is gone;
   all motion now lives inside the WebGL scene itself, driven by the pin). */

   uses this class (rebuilt into .keynote-canvas-layer, full-viewport), but
   index.html's lighter teaser still does. Without an explicit width here
