/* ============================================================================
   DEVOLITH — design system
   Art direction: "software cast in stone" — a dense, engineered monolith,
   not a hazard-striped drop-culture warehouse. Honest, real, built to last.
   Palette:  Obsidian #0B0C10 (bg) · Basalt #15171D (panel) · Chalk #EEF0F4 (text)
             Fog #939AA8 (muted) · Current #2FBF8F (primary accent, jade)
             Ember #E8874A (secondary accent, warm bronze)
   Type:     Bricolage Grotesque (display, headings) + Hanken Grotesk (body,
             UI) + JetBrains Mono (serials, keys, labels)
   Signature: the MONOLITH PLATE — a chamfered slab with a stamped serial,
              a glowing seam and a 3D tilt on pointer.
