/*
 * Avitail — public site. The app's "Flight Deck" dark palette, transcribed by hand from
 * src/theme/colors.ts (dark column) + tailwind.config.js. Deliberately a COPY, not an import: this
 * site has no build step and no dependencies, so it can never break the app's CI or need a security
 * update. If the palette is ever retuned, retune these six custom properties with it.
 *
 * No webfonts, no analytics, no third-party requests of any kind — a privacy policy served from a
 * page that phones out to a font CDN is not one. Everything here is first-party or a system font.
