/* Blog-specific styles.
 *
 * Every blog page loads /public/css/style.css FIRST, which supplies the whole
 * design system: the --light_theme/--dark_theme token sets, fonts, the fixed
 * header, .navlist, .title and the card recipe. This file only adds what the
 * blog needs on top. Don't redefine colours here — use the tokens so the blog
 * and the portfolio can never drift apart.
 *
 * Note: the portfolio's reset is `* { padding:0; margin:0; text-decoration:none;
 * list-style:none }`. That's fine for a landing page but it flattens rendered
 * Markdown, so .post-body below deliberately restores prose defaults.
