   RASA — The Proof Book (daily.html only; rides styles.css tokens)

   The artifact: a cook's proof book lying open under ONE reading lamp
   (top-left). Pages are paper — dated margin, an ink seal, the dish photo
   pasted in as the specimen, the reaction set in display serif, the one
   printed fact as a numeral. The index at the back is dense small type with
   a thumbnail of the dish that proves each unproved page.

   Lighting: the lamp is the only light. Paper is lit from the top-left
   (inset highlight) and shadows fall to the bottom-right (a short, soft
   shadow). No per-element glows. Border OR shadow, never both.
   Motion: paper settles (small drop, expo-out, staggered); a seal stamps
   once. No bounce. Reduced motion = no motion.
