/* System Duo: cream paper and ink, a serif display face, one ember accent; the family of decision.vllm-sr.ai and

   and closes at dusk on ink. Three type levels, an 8 px rhythm, motion through transform and opacity only. Fonts are
   self-hosted (SIL OFL, assets/fonts/); nothing loads from another origin, and every page reads without JavaScript. */
