   6. HERO  (the only place Three.js / WebGPU runs)

   Layout layers, back to front:
     .hero__canvas   — full-bleed WebGPU canvas (decorative)
     .hero__veil     — gentle vignette + readability scrim
     .hero__content  — brand, title, tagline, CTAs

   Fallback strategy:
     The .hero element always paints `var(--hero-gradient)` as its
     own background. When WebGPU is unsupported, hero-webgpu.js adds
     `.hero--fallback` to the section, which hides the canvas and
     animates the gradient subtly so users without WebGPU still see
     a beautiful, alive backdrop. No WebGL fallback needed.
