/* ═══════════════════════════════════════════
   Article pages — compliance cluster and every
   long-form content page that follows.
   ═══════════════════════════════════════════

   Scale, tokens and rhythm are taken from css/legal.css so a content page and
   a legal page read as one system. What is added here is the vocabulary a
   sourced compliance page needs and a legal page does not:

     .art-scope   what this page IS about — stated before the body, because a
                  scoping sentence buried under 400 words does not scope
                  anything
     .art-gap     what is NOT established. Deliberately styled as a first-class
                  block, not a footnote: the evidence corpus forbids resolving
                  an open question by picking the likelier answer, and a page
                  that whispers its gaps is doing exactly that
     .art-key     the sourced facts, above the prose, so the answer is readable
                  without reading the article
     .art-quote   verbatim statute text with its citation welded on
     .art-src     the source list. Every number on the page resolves to a row

   Mobile-first: every rule below is the 390 px rule. Wider screens are the
   media-query exceptions, never the base. Nothing here may introduce a
   horizontal scroll — wide content (tables) scrolls inside its own wrapper.  */

/* ─── Head ───────────────────────────────────────────────────────────────── */

/* NOTE — horizontal padding is deliberately NOT set on these <section>s.
   styles.css gives every `section` 100px/40px, dropping to 72px/24px under
   930px, and that 24px is the mobile gutter. Writing `padding: 104px 0 32px`
   here would silently zero it and put body text against the edge of a 390 px
   screen. Only the vertical axis is touched below.                          */
