/* Scenarios (the Digital Lab's step for envisioning future movements), in the Lab's look.
   Loaded only inside the Lab (base /comdyn), after the Lab's own /field-study/theme.css and fonts.css, which give
   every colour, the type, the stickers, the buttons and the dark/light roles. This file keeps layout and shape and
   names no colour: role tokens only (--text, --surface, --edge, ...), so the page changes with the Lab's one switch.
   The parts other files draw (the course bar, the helper, the Desk round, the built-in card example) are given the
   same look here. */
