   Namespace: .ab-*  (about page).
   The page is self-contained: it does not lean on .sec or .lp-shell because
   it alternates full-bleed background tints between sections, which the
   .sec primitive (max-width: 1200px) can't do without breaking out of its
   shell. .ab-section is the full-bleed wrapper; .ab-section__inner is the
   1200px constraint.
