   BLOG
   - /blog            magazine-style index
   - /blog/{slug}     2-column article + sidebar (mirrors .lp layout)
   Reuses base.css design tokens (--container-max, --gutter,
   --section-y, --stack-*, --radius-*, --ink, --brand, --muted).
   Prose typography is tuned for 45+: 18px body, 1.7 line-height,
   65ch measure, generous vertical rhythm.
