/* ============================================================
   ARTICLE / LONG-FORM GUIDE LAYOUT
   ------------------------------------------------------------
   A plain reading column for guide pages that should read like
   an article, not a landing page. No cards, no grids, no boxes —
   headings, paragraphs and lists in one measured column.

   Uses the "embassy paper" tokens from styles.css (paper/ink,
   Fraunces display, IBM Plex Mono labels). Light theme only,
   matching the site's `color-scheme: only light`.
