/* Static blog styles.
 *
 * Light theme only, matching the marketing and documentation pages. The blog
 * loads /marketing.css for the shared header and footer chrome and
 * /documentation.css for the article prose typography (.documentation-content).
 * This file adds only the blog-specific layout: the single centred column, the
 * index post list, and the post header (title, meta, back link).
 *
 * Plain color literals (not the app's semantic tokens), like documentation.css.
