 * Everything is namespaced afd-* so it cannot reach the shared nav, footer or
 * theme styles. No element or bare-class selectors outside .afd-* / #afford-*.
 *
 * Colour notes: brand teal #48A3A6 is 2.97:1 on white and FAILS WCAG AA for
 * text, so it is used only for rules, fills and borders. Teal *text* on a light
 * ground is #2E7D82 (4.6:1). Body text is #012F38 on #fff (14.8:1) and the
 * muted grey is #5a5a5a (7.0:1).
