/* Rodaki design tokens.
   Palette origins:
   - clay      #C9553D  paint on courtyard swings and benches
   - moss      #4A7C59  park greenery / "verified" signal
   - paper     #FAF7F2  recycled paper of a school notebook
   - ink       #1F1B17  warm near-black, never pure #000
   Neutrals are warm-shifted (hue ~30) to match the paper base. */
