/* router.css — the entry page.
 *
 * This page exists to be replaced within a frame or two, so it is kept small.
 * It is a file rather than an inline <style> because the CSP says
 * `style-src 'self'` with no 'unsafe-inline', and one extra request on the one
 * page nobody looks at is a fair price for a policy that holds everywhere else.
 *
 * It is also the only stylesheet here that answers to the system theme. Every
 * other surface is light-only and deliberately so — a half-built dark theme is
 * where contrast bugs live and where a status colour quietly stops meaning what
 * it means. This page has no status colours on it, so it can afford to be
 * polite about a dark phone at six in the morning.
