/* modules/blog/assets/blog.css — the public blog surface (listing + a single post).
 *
 * Scoped under `.blog`, exactly the way modules/forums/assets/forums.css scopes under
 * `.forums`: a theme's own rules keep the page around it, and every colour, radius, shadow
 * and font reads the theme contract's --cms-* tokens (site/themes/README.md section 6). A
 * theme that defines them restyles the whole blog without touching this file.
 *
 * Blog never shipped its own stylesheet before this file — its two views were written in
 * the private class vocabulary of a theme that never lived in this repo at all, so /blog
 * rendered unstyled on every fork except the one nobody could see. Unlike forums, there is
 * no pre-1.5.0 name to fall back to here: blog never read a custom property at all before
 * today. So each token reads --cms-* first, then a currentColor-derived neutral, which
 * adapts to a light or a dark theme on its own where a literal cannot.
 *
 * ⚠️ Body text falls back to currentColor UNDIMMED, and that is deliberate. `.blog` sets its
 * own color from this token, so a descendant that derives from currentColor again multiplies
 * the alpha: 0.78 x 0.78 = 0.61, about 2.7:1 on white, below AA. A module has no business
 * making the theme's body text lighter than the theme set it — only muted and meta text is
 * dimmed, and only once.
 *
 * The plain literal before each color-mix() declaration is the intended value written out so
 * a reader can see it, NOT a runtime fallback: a custom property accepts any token stream, so
 * the color-mix() line always parses and always wins, and an engine without color-mix()
 * computes the token to inherit/initial rather than to that literal.
 *
 * Two breakpoints (960px, 620px): the card grid runs 3 columns, then 2, then 1. */
