/* NextMate public site.
 *
 * Deliberately one stylesheet, no build step, no framework: the whole site is four
 * static pages, and Cloudflare serves this file as-is.
 *
 * Fonts are self-hosted rather than linked from Google Fonts. A font CDN sees every
 * visitor's IP address on every page load, which is exactly the kind of third-party
 * data flow this site's own Privacy Policy says NextMate does not do — linking one
 * from the page that hosts that policy would make it untrue. The woff2 files are
 * subset to Latin plus the punctuation the legal text uses (~16KB each, down from
 * ~340KB); regenerate them with scripts/build-website.py.
 *
 * Colors are taken from apps/mobile/src/theme.ts. Keep them in sync by hand: this
 * file cannot import from the app, and a web build step purely to share six hex
 * values would cost more than it saves. */
