   8. HERO — PROJECTED HOLOGRAPHIC FACE
   A scanned human head (glTF bake, streamed as static/models/head.holo) is
   rendered by static/js/holoface.js in raw WebGL: additive fresnel shell +
   wireframe + surface stipple, with scan bands, band tearing and RGB split.
   Everything around it — cone, emitter, motes, scanline rake, HUD ticks — is
   CSS, and the chromatic veil reads the --holo-glitch value the renderer
   writes each frame. Falls back to the baked poster with no WebGL or no JS.
