/* Shared look for every lab in static/lab-tools/. Matches the docs site (Docusaurus / Infima): MARS/WARS red,
   Infima neutrals, system fonts, 0.4rem radius. Layout and component styles are adapted from FRC Team 1756
   Argos's PID Tuning and Pose Estimator labs (BSD 3-Clause, see static/lab-tools/THIRD_PARTY_NOTICES.md).

   A lab links this file, then lab-theme.js, then adds only its own styles. Data colours (--actual, --goal ...)
   are shared so the same idea is the same colour in every lab. */
