   KNOWLEDGE HUNT — components
   ------------------------------------------------------------
   Aesthetic: sticker-book arcade. Chunky strokes, hard offset
   shadows (no blur), oversized display type that tilts and
   breaks its box, speech bubbles as the structural motif,
   trading cards for the collection, and a high-score board
   that behaves like an arcade cabinet.

   All colours/fonts come from tokens.css. Never hard-code a
   colour here: it would break skinning.
