/* ============================================================================
   Palm Valley Church - Sermon Archive

   The palette is the church's own brand cyan, sampled from the logo lockup:
   #00AFE5. That colour is only 2.47:1 against white, so it can never be text -
   it is used for fills alone (spine bars, badges, the mark, focus). Interactive
   text uses a deepened version of the same hue that clears WCAG AA.

   Light only, by request. Every text colour below is measured against --paper:
     --ink 15.42:1   --muted 5.73:1   --brand-deep 5.55:1   --brand-strong 7.00:1
   The cyan hairline recurs as the only divider in the page.
