/* Paper: the shared marketing frame for the sandbox hubs. Taken from the PAP Sandbox hub (public/css/pap-hub.css,
   papchecker.com's look): paper ground, Newsreader display with an italic accent, Hanken Grotesk body, JetBrains Mono
   labels, the dark announcement bar, mono nav, white cards on hairline rules, the four-column footer.
   Used by the UCP Sandbox hub (layouts/hub, docs). pap-hub.css carries the same rules for the PAP hub and can
   switch to this file with one <link>. Product-specific pieces live in each hub's own file (hub-paper.css).
   Self-contained tokens; light only. Text colours meet 4.5:1 on --paper and --card. */
