/* 17b. DARK CONTEXT INHERITANCE ===========================================
   Several surfaces are dark without carrying the .surface-ink class, the
   hero, full-bleed image bands, the footer and the mobile drawer. This block
   gives all of them the same light-on-dark treatment in one place, so a
   component dropped into any of them reads correctly. It sits after the
   component definitions so it wins on order, not on specificity hacks.
