/* ═══ k1r1l0v · THE STUDIO IDENTITY ═══════════════════════════════════════════════════════════
   Distinct from AURUM's night-gold on purpose (his direction, 2026-07-10): the studio is DARK
   ENGINEERING LUXURY — cold precision, one electric accent, monospace details, hairline rules,
   fine micro-motion. Zero external requests: system type, CSS-drawn everything.
   AURUM appears on the landing only as an artifact in a vitrine — the warm jewel in a cold frame. */
