   Layer: sections

   Table of contents
     1. Page base ................................... body.page-legal
     2. Legal header band (dark, under the fixed header) ... header.legal__head
        Breadcrumb (ol > li, separators drawn here), eyebrow, h1, "last updated"
     3. Reading column ............................... div.prose (max 72ch)
        h2 with a small sunset ridge accent, h3, p, lists, links, strong, tables, hr, address
     4. Call-to-action card .......................... aside.legal__cta
     5. 404 page ..................................... main.error-page

   Notes
   - The header is always in its condensed, solid state on these pages (is-scrolled is-static),
     so the dark band starts below a condensed header height.
   - Links in running text are underlined in --color-accent; the hover thickens the line
     instead of changing the color, so contrast on paper stays at 5.6:1 (AA).
