/* Blog index — filter strip and post cards.
 *
 * ADAPTED FROM the "Index / filter page" block in src/blog-static/blog.css, which
 * has shipped to production since the blog launched and been DEAD the whole time:
 * the 18 posts load blog.css and use only `.filter-pill` as a decorative label,
 * while /blog/ renders through base.njk and never loads blog.css at all.
 *
 * THREE MANDATORY CHANGES on the way over, each of which would otherwise be a bug:
 *
 *  1. `.card-grid` → `.post-grid`. site.css:114 ALSO defines `.card-grid`, with a
 *     different grid, so keeping the name means this stylesheet silently reflows
 *     /tenders/, /glossary/ and /funding/ the moment any of them loads it.
 *  2. `.piece-card` → `.post-card`, and the `.is-planned` / `.is-backlog` /
 *     `.status-dot` / `.type-tag-*` states are dropped. They describe an editorial
 *     pipeline; these are 18 published posts.
 *  3. Every hardcoded hex becomes var(--token, literal). /blog/ has the tokens
 *     today, but radar.css's header records what happens to a stylesheet that
 *     assumes them: it applies and still renders nothing.
