/* ════════════════════════════════════════════════════════════════════════
   luaur — visual identity (Brand Book 1.0)
   ────────────────────────────────────────────────────────────────────────
   Concept: "C++ to Rust, reimagined." Graphite machined ground, a sharp
   engineering-drawing grid. Cyan Teal is the primary signature — links,
   primary buttons, key stat numbers, the hero gradient. Rust Orange is a
   rare warm secondary accent. Headings and prose set in Satoshi (geometric
   sans, clean + confident); code, labels, eyebrows and stat numbers in
   JetBrains Mono. The </> bracket monogram is the mark.
