/* claude.css — shared surface + components for the "designed by Claude" prototypes.
   Builds on colors_and_type.css tokens (cream/paper palette, fonts, easing).
   Design thesis (see each viewer page's doc): numbers are the hero, the home is a
   worklist not a dashboard, settle is deliberate and honours the two-party
   confirm-receipt model, and the first real session is a designed state — never a void. */
