/* 5-String Banjo Chords: the app's own "Walnut" look (Banjo Chords D3): dark walnut, calfskin
   cream, one copper accent, and patina green that only ever means the short 5th string. The
   colours are the app's tokens (play/styles/app.css), so the page, the live chord box and the
   screenshots agree.

   Loaded AFTER ../style.css on every page in this folder: it re-points the house variables, so
   privacy.html and support.html take the look with no markup changes, and adds the components
   only index.html uses. No web fonts from anywhere else: the accidentals font is the app's own
   file under play/styles/, the serif stack is the app's. The app is dark only, so this page is too. */
