 * for blog content: every post and the index pages share the same
 * typography and accents, so the rules live here once.
 *
 * The blog uses a slightly different reading-typography stack from the
 * marketing pages — DM Sans for body, generous 1.75 line-height, a
 * 720px content column — because long-form prose has different
 * legibility needs than a marketing layout. The brand palette
 * (--bg, --cyan, --border) still comes from site.css :root so nav

   collapse the full nav to the hamburger below 1200px — so the full nav
   only ever shows, in compact form, at ≥1200px. blog.css had drifted out
   of sync: it kept the site.css 2rem wordmark at every desktop width and
   only collapsed at ≤900px, so the oversized brand (≈438px vs the home
   page's ≈297px) shoved the nav rightward until "Sign in" wrapped onto a
   second line — the header misalignment. These two queries restore parity.
