Fonts are self-hosted now
The site used to pull its two typefaces from a font CDN, which meant every visitor's browser announced itself to a third party before the inbox had even loaded. Both fonts now ship from this server.
- No font CDN request, so no third party sees your IP on page load
- Fonts are preloaded and cached for a year — text stops shifting around on first paint
- CSS and JS now carry a one-hour cache with stale-while-revalidate; HTML is always revalidated so updates are never stale
