/* HELIX — Typography tokens
   Three roles, one scale:
   · Plus Jakarta Sans 600–800 — display, titles, big numbers, wordmark
   · Inter 400–700 — all body, labels, buttons
   · JetBrains Mono 400–700 — position codes, stats, the clock, anything tabular
   Sentence case throughout. Mono is for data only, never body. */
