   Batsky — batsky.ai

   Values (colours, sizes, spacing, radii) are lifted from the design mockup at
   design/Main-html/Main.dc.html, which is authored against a fixed 1440px
   artboard. Where the mockup gives one fixed number, this sheet expresses it as
   a clamp() between a phone-sized and the artboard value so the page holds its
   proportions at every width.

/* --------------------------------------------------------------- fonts --
   Self-hosted subsets of Chakra Petch / Space Grotesk / JetBrains Mono
   (latin, latin-ext), generated by tools/fetch-fonts.sh. Served from our own
   origin so there is no third-party DNS + TLS handshake in front of first
   paint.

   These live here rather than in their own stylesheet on purpose. As a
   separate file the browser could not discover the woff2 URLs until that
   file had itself been fetched and parsed — HTML -> fonts.css -> woff2, a
   three-hop critical path. Inlined here, plus the <link rel=preload> tags in
   the document head, the fonts start downloading alongside this stylesheet.
