/* GPT Marlon — guides section.
   Tokens come from theme.css (imported by site.css).
   Reading structure follows the long-form guide pattern: prominent PDF CTA,
   a table of contents, numbered sections, and copyable prompt blocks.

   v2 (Block 1, 2026-09): adds the sticky/mobile-sheet TOC, the numbered-step
   wrapper, four callout variants, and install-steps — see the block at the
   bottom of this file. This is a NEW FILENAME, not an in-place edit of
   guides.css, specifically so the old immutable-cached file (vercel.json:
   /assets/(.*) -> max-age=31536000) is simply never requested again instead
   of risking a stale-cache/new-markup mismatch window. guides.css stays in
   the repo unmodified until every guide is migrated to blocks (see
   ../TODO.md), then gets deleted. */

   No `wide` breakout variant: the image lives inside .guide-main, which is

   rail) — a descendant nested inside a grid item can't span the parent
   grid's columns (grid-column only affects direct children), and the rail
   occupies column 2 for the page's full height regardless of its own
   content height, so a negative-margin bleed wide enough to matter would
   render underneath/through the sticky rail on any guide with a TOC (most
   of them). Every image is content-width, matching every other block. */
