/*
 * SEO / LLM-citation static-page stylesheet
 *
 * Ships as ONE file, no external assets, no fonts, no images. Loads
 * from /blog/seo-styles.css (copied there by the generator). Every
 * static page written to public/blog/** links this stylesheet at the
 * exact same absolute path.
 *
 * Design intent: readable, dated-feel document. Not trying to match
 * the SPA hero styling — these pages exist for crawlers and users who
 * followed a search-engine link. Optimize for legibility + zero CLS.
