/* ═══════════════════════════════════════════════════════════════════════
   QUINTALUZ  |  V5, the descent as full-screen chambers
   Near-black. One hue at a time. Every moment is a 100dvh chamber that
   snaps into place, each with its own slow generative background in the
   metatron spirit. Inscriptions, not paragraphs. An artwork first, a
   website reluctantly. Lowercase everywhere; spectral afterglow on display.
   Type: Space Grotesk (self-hosted, variable weight).
