/*
 * Routeser marketing stylesheet.
 *
 * Every colour comes from /tokens.css, which build.mjs generates from the console's
 * own `:root` block — this file must never introduce a palette value of its own, so
 * the public site and the product stay the same shade of everything. (The only raw
 * keywords below are `black`/`transparent` inside `mask-image`, where they are alpha
 * channels rather than palette colours.)
 *
 * Component shapes mirror the console: 1px `--border` hairlines, `--radius-*` corners,
 * near-black primary actions, emerald `--success` accents, Geist at 500-600 weight with
 * tight tracking, and the console's two-layer `enterprise-shadow`.
