/* Public styles.
 *
 * Deliberately free of scaffold tokens. A title is free text, and one that
 * happened to close a CSS comment would leave the rest of this file as
 * broken CSS on a live site.
 *
 * Flask serves this directory at /static, so anything you drop in here is
 * reachable at /static/<name>. Stylesheets, images, fonts and downloads all
 * belong here rather than in templates/.
 *
 * The theme variables and the pre-paint script stay inline in
 * templates/index.html on purpose: both have to apply before the browser
 * paints, and a stylesheet is a round trip that arrives too late. Everything
 * that can wait lives here.
 *
 * No third-party fonts, analytics or CDNs. Self-host whatever you need.
