/* Korjin — article (single blog post) page. Long-form editorial layout:
   reading-progress bar, post header, framed hero, narrow reading column with
   pull-quote + ordered list, inline promo card, and a "Keep reading" row.
   Tokens/spacing/typography come from tokens.css + base.css + components.css;
   .crumbs, .title-xl/.title-lg, .label--accent and .eyebrow are already global,
   so this file only adds the .readbar + .art__* + .pullquote layer. Mirrors the
   source article.html / js/pages/article.js. */
