/* hub.css - the public hub and the workshop. Load AFTER tokens.css (the console's own sheet,
   copied beside each page by hub/generate.py), so the hub and the console are one palette.

   A document, not an app shell: the page scrolls, there is no script, and every colour, size,
   radius and shadow below is a token. No literal belongs here; a new colour goes in tokens.css
   and through the contrast test first. */
