   SELF-HOSTED FONTS
   Poppins was previously loaded from fonts.googleapis.com, which meant two
   cross-origin DNS/TLS handshakes before the first pixel of UI chrome could
   paint, and a third-party dependency for a privacy-first product. The four
   weights actually used by this app (300 for "Notes", 500/600 for the
   wordmark, kickers and popover titles) are now served from ./fonts.
   Latin + latin-ext subsets only: the devanagari subset the CDN also shipped
   was pure dead weight for an English-language app.
