/*
 * The public pages' whole stylesheet. Hand-written rather than generated: most
 * of what it styles is long-form prose and rendered markdown, which carry no
 * class attributes for a utility framework to hang on.
 *
 * It reproduces the SPA's frosted-glass look (GlassBackground.tsx: the photo, a
 * 40% black overlay, translucent blurred cards) so a reader moving between a
 * public page and the login sees one site. The tokens below are that look,
 * written down once; when GlassBackground or glassCard changes, change them.
 *
 * No remote fonts and no remote images. The backdrop is the same photo the
 * React pages pulled from Unsplash on every view, now served from this origin
 * (/background.jpg): a marketing page should not depend on a third party being
 * up, nor tell one who is reading it.
