/* datamusak — "early-MTV × 90s demoscene".
   Pure black. Colour comes only from objects. The logo is the one wild hero; the rest is calm,
   but alive: glossy plastic stickers (fat #050505 outline, hard offset shadow in another hue,
   chrome stripes on the upper half, hard white specular), checkerboards on secondary surfaces,
   yellow/cyan zigzags, low-cadence steps() motion, and a VHS glitch only on interaction. */
