/* Trenyx — site design system v3 (2026-09-07). Static, one CSS file, no JS.
   Voice: a published record, not a terminal. Light-first, cool off-white ground,
   verdigris accent (a seal), ink-biased neutrals. Dark theme redefines tokens only.
   Type: Fraunces (display) · Source Sans 3 (body) · JetBrains Mono (hashes, ids, verdicts).
   Every class name from v2 is kept, so page markup and copy are untouched. */
