   VERSION: 1.0.0
   DATE CREATED: 2026-08-06
   PURPOSE: Unified design system for the AviaSAFE platform.
            Light palette (off-white background, deep-navy text, teal accents),
            Inter typography, refined components for landing, login and shells.
            Loaded AFTER /css/main.css so it can extend and refine shared tokens
            and components without touching the functional layout styles.
