   Drop this into any HTML file and you get the full Meterless token
   system plus the semantic classes (.display, .section-h, .btn-dark,
   .pill, .mono-label, etc) used across the marketing site.

   Geist and Geist Mono are VENDORED (css/fonts/), not pulled from Google
   Fonts. The remote @import broke twice over: the app's CSP does not allow
   fonts.googleapis.com in style-src, so the webview refused it outright,
   and a desktop app that must work offline cannot depend on a CDN — nor
   should a process holding API keys announce every launch to one.
