   peerd blog — shared styles.
   Mirrors the locked design system from the landing + docs pages (same tokens,
   wordmark, nav, footer) and adds blog-only layout. House rules: dark mono +
   one rainbow accent, terse voice, no em-dashes. Pages link this so a token
   change is one edit, not one-per-post.
