/*
  SELF-HOSTED FONTS — activation steps:
  1. Go to fonts.google.com, download "DM Serif Display" and "DM Sans"
  2. Extract the woff2 files and place them in assets/fonts/:
       DMSerifDisplay-Regular.woff2
       DMSerifDisplay-Italic.woff2
       DMSans[opsz,wght].woff2   (the variable font covers all weights)
  3. Delete the two Google Fonts <link> tags from index.html
  The @font-face rules below are already wired — just add the files.
