/* ConformerLab app styles, from the "ConformerLab Screens" design.
 *
 * Tokens and components are the design's own, carried over verbatim so the
 * pages and the canvas cannot drift apart. Two things are added around them:
 * the theme is chosen on <html> (OS preference by default, the toggle wins
 * both ways), and the older token names that structure-view.js and viewer.js
 * read are mapped onto the design's, so those modules follow the theme too.
