   Mobile edition primitives (2026-10-24)
   The same HTML on the same URLs for every device. On phones (≤1023px) a page
   opens on its digest and folds its long sections into chapters; desktop and
   no-JS render everything open. Nothing here changes layout above the fold
   boundary. See docs/site/content-and-pages/design-system-and-frontend.md.
   ========================================================================== */

/* Chapter — a foldable section ----------------------------------------------
   Markup contract (static, author-visible, nothing hidden without JS):
     <section class="chapter" id="…" data-screen-label="…">
       <h2 class="chapter__title">…</h2>
       <div class="chapter__body">
         <p class="chapter__lead">first paragraph, unchanged</p>
         …the rest of the section, unchanged…
       </div>
     </section>
   Folded, a chapter shows its title, its lead (two-line clamp) and anything
   marked .chapter__keep (an eyebrow, say); every other element is hidden, and
   the wrappers around the kept ones stay. So the title and lead may sit inside
   layout wrappers (the homepage sections do), and .chapter__body is optional:
   use it where the rest is a free block — js/main.js wraps that block in
   <div class="chapter__rest" hidden="until-found"> so find-in-page and text-
   fragment links reveal it (beforematch → open).
   The one-line gate in <head> adds `js` to <html> before first paint; the fold
   rules below are scoped to it, so no-JS never folds and nothing shifts after
   paint. js/main.js wraps the title text in a <button class="chapter__toggle">
   while the phone layout is active, and restores the static DOM above it.
   A chapter that is the hash target, or contains it, is always open.          */
