/*
 * The Links homepage, drawn in Nocturne — the app's own design system.
 *
 * Values are lifted from src/theme/nocturne.ts so the page and the screenshots
 * on it are the same palette. Inter is self-hosted from /fonts (OFL), because
 * a page that promises "coordinates never reach us" should not ship its
 * readers' IP addresses to a font CDN. The app is dark-only, and so is this
 * page: the screenshots would look wrong on anything else.
