Fonts

fonts:
  sans: Inter
  mono: Fira Code
  selfHost: true

fonts follows Slidev: sans, serif, mono, local, weights, italic, fallbacks and provider. A provider is google, coollabs, none, or the address of a Google-compatible css2 endpoint.

By default the fonts are an @import from the provider, so the deck needs the network when it is shown. slide.ng adds selfHost: true, which makes the build download the provider's style sheet and every font file in it and serve them from media/. It is on by default with pwa: true and with build --offline, and selfHost: false turns it off. If the download fails the build warns and the deck keeps the @import.

A theme's fonts are merged with the deck's fonts key by key, so fonts: { mono: 'Fira Code' } keeps the theme's sans. fonts: { provider: none } loads nothing.

The download runs on the machine that builds, so build decks from others without selfHost.
