/* ST SAFE TRAVEL — Elegant travel advisor
 *
 * Design language: clean, refined, airy. No glassmorphism, no neon.
 * Light sky-paper background (flat, MAS-like) with a soft sky glow on top;
 * slightly translucent white cards, thin borders, soft shadows.
 * Work Sans light weights, muted palette, sky accent used sparingly.
