/* The public setup guide of Tlačomat, in the Školomat design system like the app: white and one quiet grey, near-black
   type, one calm violet, rounded cards, pill buttons, soft shadows. Colours, radii and shadows come from tokens.css
   (deploy.py copies the app's copy of the workspace's Brand/tokens.css next to this file); --tlac marks the steps.
   The greys of the drawn Windows dialogs are Windows' own, not the brand's. Everything that moves is
   transform/opacity/clip-path, and everything is already in place when JavaScript or motion is off. */
