/* styles.css — license scanner
   Visual direction: the world this lives in is motorcycle range training —
   asphalt, hi-vis safety gear, painted lane lines. Base is dark asphalt so a
   bright camera viewport and the scan reticle carry the screen; the single
   accent is hi-vis safety yellow, used only on the primary action and the
   reticle, nowhere else. System font stack on purpose: this runs on a student's
   phone in a parking lot on a weak connection, and a web-font that fails to
   load would degrade the one screen that has to work. Reliability is the look. */
