   Damage Code Tool - RASTools Design System
   Unified flush board on desktop, app-style step flow on mobile.
   Brand: navy/crimson chrome; green = completed, red = danger.
   NOTE: the mobile progressive-disclosure mechanics (media query
   step machinery, fixed panels, show/hide classes) are load-bearing
   for js/damage-code.js - restyle freely, but do not change the
   display/position semantics without testing the full flow.
