/*
  DESIGN SYSTEM — "sticker-toy"
  One mechanical rule, applied identically in this file and in the canvas
  drawing code (src/game.js): every shape is a flat saturated colour fill,
  a uniform thick ink outline, and a solid, unblurred, offset "peeled
  sticker" shadow. No gradients, no blur, no paper-grain texture, no pastel
  washing — anywhere. Text sits on every coloured surface in the same ink
  colour, never white, so contrast never has to be special-cased per
  variant. The shadow is the interaction language: it grows on hover (the
  piece lifts off the page) and collapses to nothing on press (it's
  stamped flush against the page) — see button rules below.
