   This used to be a <link> to fonts.googleapis.com. That put TWO third-party
   origins on the critical path — googleapis for the CSS, then gstatic for the
   files it named — and neither could start until the one before it finished. A
   DNS lookup plus a TLS handshake, twice, before any text could render.

   Served from our own origin the whole chain disappears: the browser is already
   connected, and the @font-face below names the file directly rather than
   pointing at a stylesheet that points at a file.

   ONE VARIABLE FONT, not four static weights. Google's default answer is a file
   per weight — 400, 500, 600 and 700 were four separate requests. The variable
   cut carries the whole 400..700 axis in a single 30KB file, which is both fewer
   round trips and strictly more type: app.css asks for `font-weight: 650` in two
   places, and with static weights the browser had no 650 to give and synthesised
   one. Now it is a real instance.

   The unicode-range split is kept exactly as Google served it. It is what stops
   a page of English pulling the 11KB latin-ext file it will never draw from.

   Instrument Sans is licensed under the SIL Open Font License 1.1, which permits
   self-hosting. Files are the woff2 cuts from Google Fonts v4.
