/* Self-hosted Geist and Geist Mono (OFL, see assets/fonts/LICENSE): latin and latin-ext subsets,
   same unicode-range as Google Fonts. 'Geist Fallback' is Arial resized to Geist's metrics so the
   swap does not move text: size-adjust is the Geist/Arial width ratio measured on the site's own text
   per weight (400 and 500 on Arial, 600 on Arial Bold; 400 and 500 nudged to the first-screen h1 and
   lede), the overrides give Geist's 1005/295 ascent and descent, and its unicode-range is Geist's, so
   glyphs Geist lacks (the arrow) still come from the system font. A ch unit follows whichever font is
   showing, so the text measures that used ch are written in em at Geist's zero width (0.663em at 400,
   0.673em at 500): same width with Geist, no reflow on swap. */
