/*
  Fireloop Forge: marketing site (Home + Solutions/Forklifts)
  Direction: quiet, light, monochrome with a single accent (Fireloop indigo), in the spirit of antioch.com.
  Colour discipline: neutrals do the work. --accent marks one thing per view. Pass/fail colours only on results.
  Motion: everything is readable at rest; animations run only under .play / .on and respect reduced motion.
