/* ============================================================
   Syndie · Design tokens
   Cohere design language, translated for Syndie.
   Rules carried over verbatim from the reference system:
   - Surfaces separate by tone (canvas → cream → ink), never by shadow.
   - One hairline weight for every border.
   - Radius grammar is a closed set: 4 / 8 / 22 / 9999.
   - The primary action is an ink-filled pill. No colored CTAs.
   - The chromatic gradient lives in imagery and washes only.
   - Brand green appears as punctuation, never as a surface.
