/*
 * The blog's own styling.
 *
 * Why this exists at all, when the page already links the site's compiled
 * Tailwind: that stylesheet is *purged*. Tailwind scans the source it is built
 * from and emits only the utilities it finds there, and a PHP file it has never
 * seen is invisible to that scan. Checking the built CSS shows exactly that —
 * `prose`, `leading-relaxed`, `object-cover`, `aspect-video` and `py-14` are
 * all absent, because nothing in the React site uses them.
 *
 * So this page takes the *tokens* from that stylesheet rather than its classes.
 * --color-primary, --color-dark and the --text-* scale are custom properties
 * emitted by Tailwind v4's @theme block, so they are there whatever the purge
 * decided, and a change to the site's palette moves this with it.
 *
 * Every var() carries a literal fallback: if the compiled stylesheet is ever
 * missing — a failed build, a half-finished deploy — a blog post should still
 * be a readable page rather than unstyled text.
 *
 * Dark mode matches the site: `.dark` on <html>, set by the inline script in
 * PublicPage and toggled by blog.js.
