/*
 * Landing page styles.
 *
 * An external stylesheet rather than an inline <style> block, because the content security policy sets
 * style-src 'self' with no 'unsafe-inline'. An inline block is blocked outright, which renders the page
 * in the browser's default serif on a transparent background — and does so silently, with only a console
 * warning. Keeping the policy strict and the styles external is the right way round.
