 * "Ocean Breeze": white ground, a deep twilight navy, one bright teal blue for everything you
 * can press, turquoise and two icy tints for accents — the same five colours as the terminal and
 * the wallet app. Hairline borders, system fonts. Nothing is loaded from a CDN — these pages are
 * served by the platform itself and have to work on a campus network with no route to the
 * internet, which is exactly where the terminals live.
