   AlloyTechs — tokens & primitives
   Mirrors /var/www/alloy-automotive/src/styles/global.css so the two
   properties read as one brand. There is no build step and no shared
   import here, so the two files are kept in sync BY HAND. If you change
   a token there, change it here too.
   Display + spec labels: Manrope · Body: Open Sans. No third face.
