/* pp-article.css - Lab article component sheet.
   2026-09-22, scoped pass (PRE-BUILD-CHECKLIST B1-B4). Staged on an UNPUBLISHED theme copy.

   SCOPE. Every selector below is prefixed with `.pp-article`, the wrapper class added to the
   article body div in blocks/_blog-post-content.liquid (it sits on the same element as
   `.blog-post-content.rte`). Nothing in this file can reach the header, the footer, the
   "More from the lab" module, /pages/tools or any other surface that already uses a pp- class.
   Proof: `python scope_check.py` - 0 selectors outside the wrapper, 0 live collisions.

   The root block uses `.pp-article.pp-article` (0,2,0) on purpose, so the article measure and
   type scale beat the theme's own `.blog-post-content` (0,1,0) without depending on which
   stylesheet the browser happens to see last. Same trick the theme already uses in
   snippets/pp-article-footer-rhythm.liquid.

   FONTS (decision 3). Headings move off Trirong onto the BODY font the theme already loads,
   via `var(--font-body--family)` = Red Hat Display (config/settings_data.json:17). Using the
   theme's own variable means no new webfont request and - answering AUDIT-CODEX section 2 -
   NO body font change at all: the body keeps exactly the family it renders today.

   Brand: #F7F6F3 ground, #101418 ink, #1E4FD8 accent. Ryze proportions: tracked micro labels,
   hairline cards, a visual block about every 200 words. */
