/* zizo.css: "The Menu in the Chat"
   On / and /products/college-platform every section is a pair: the mess colleges described (a flat
   group chat, their own words as italic callouts) on the left, and where it lives instead (the
   college's own app, a flat white panel) on the right, joined by one 2px ink connector.
   Every other public page (products, services, about, privacy, 404) uses the "Reading pages"
   section at the end: ruled rows on the same paper. The /for/ previews keep landing.css.
