/* ─────────────────────────────────────────────────────────────────────────
   Follis site styles: ink and bronze.
   The same palette as the app (budget_app/src/app.css), and the same shape as
   the Deckle site this theme was ported from, turned the other way up: Deckle
   is a dark page with cream sections, Follis is a paper page with ink sections.
   A money site reads as more trustworthy light, and the ink sections are where
   the app itself is shown, since that is how most people run it.
