/* The public pages: home, buy, terms.
 *
 * The app itself (app.css) is built for one hand and a phone at arm's length,
 * and stays that way. These three pages are the other job: someone reading on
 * a laptop, deciding whether this thing is real. So the column opens up, the
 * type scale grows with the viewport, and the sections become a layout rather
 * than a stack — while the same tokens, colours and dark mode carry over, so
 * the site and the app are recognisably one thing.
 *
 * Loaded after app.css, and only by those three pages. Everything is additive:
 * at phone width this is still a single column. */
