/* stabilis — classless theme
 * ============================
 * Minimal, monospace, single teal accent, system light/dark.
 *
 * Everything is styled through *semantic element selectors* (h1, p, a,
 * blockquote, pre, table…) rather than classes. That's deliberate: your
 * markdown is rendered to bare tags, so a classless sheet is what makes
 * post bodies look right without annotating every post. The only two
 * classes styled (.tag, .content, .task-list-item*) are the ones your
 * templates / GFM output already emit.
 *
 * To reskin: change --accent (one line). Everything else is monochrome.
