/* Tailor's site.
 *
 * The app is graphite with one blue accent, and the site is the same room —
 * so the download and the thing you downloaded do not look like two products.
 *
 * Dark only. Tailor is a tool you sit in front of at night, its own chrome has
 * no light mode worth the name, and a light stylesheet nobody checks is worse
 * than an honest `color-scheme: dark`.
