   UECF.NET — The Prayer Bible
   PDF reading-app stylesheet. Shares UECF.NET's site palette (navy / gold /
   cream / maroon / teal, Fraunces + Source Sans 3) and reading-app
   conventions already established by /study-bible/ (sticky header, mobile
   app bar, dark/light theme via [data-theme], font tokens) so the Prayer
   Bible feels like part of the same family of Bible readers.
