/* School Money — deck.css (unit C2): the /deck/ presentation page. Loaded only there, after app.css.
   Uses the app.css tokens only, so light and dark follow prefers-color-scheme.
   Screen: one slide at a time, 16:9, scaled with the page (sizes inside a slide are in cqw, a share of
   the slide's own width). Below 640px a slide may grow taller than 16:9 so its text stays readable.
   Print: one slide per landscape 16:9 page, in light colours, with the site chrome hidden. */
