/*
 * Styles for the PHP-rendered parts of the blog (list, cards, article,
 * related articles, share buttons). Plain CSS on purpose: the site's
 * Tailwind build only contains classes the React app uses, so classes
 * written in PHP templates would not exist there.
 *
 * Colors / fonts mirror tailwind.config.js and index.css of the React app:
 *   ink #1c2420, brand #2f8f5b (dark #236f45), brand-50 #eaf6ef,
 *   headings = Fraunces, body = Inter (both loaded by the app's CSS).
 * Page-wide resets (Tailwind "preflight") come from the app's CSS too.
