/* Blog styles — shared by /blog/ and /blog/article/.
 *
 * THE ONE STYLESHEET ON THIS SITE, and it is a deliberate exception. Every other page
 * carries its own <style> inside <helmet>, and infra/stamp.py keeps the shared parts of
 * those blocks identical across 21 files. That works because those blocks ARE shared by
 * every page: a new stamped region has to exist on all of them or --check reports it
 * missing. These rules belong to exactly two pages, and the card styles are used by both,
 * so the choice was a stamped region skipped on nineteen pages, the same 200 lines pasted
 * twice, or one file. One file — and only the two pages that need it pay the request.
 *
 * Everything here is written against the same tokens the inline blocks use:
 * var(--accent,#62A8FF) with the literal fallback (site-motion.js writes --accent at
 * mount, so a bare var() renders unstyled before JS boots), #9a9aa2 body text, #6a6a72
 * mono labels, rgba(255,255,255,.1) hairlines, and calc(<px> * var(--s)) on anything with
 * a px cap so the ≥1600px scale gate reaches it.
 */

/* ── shared: heading block, status line, chips ─────────────────────────────────── */

/* blog.js hides and shows the filter row, the load-more button, the status line and the
 * related-posts rail by toggling the `hidden` property. The UA stylesheet backs that with
 * `[hidden] { display: none }` at specificity 0,1,0 — which any class rule below that sets
 * a display beats, so `.bp-filters` and `.bp-more` rendered even while hidden (an empty
 * chip row, and a "Load more posts" button on a single-page listing). Restoring the
 * attribute's authority here is the fix that keeps the display values where they belong. */
