   Quiet Ink, as in the app: one interactive colour (teal), Literata for
   headlines, Instrument Sans for text, JetBrains Mono for numbers and prices.
   The pool-tile mosaic sits dim behind the header and hero only, never behind
   body text. Self-hosted fonts, no third-party requests, no trackers. */
