   FlyEstimate — Design System
   Instant per-parcel property estimates for contractors (roofing, lawn,
   siding, gutters, solar, etc). Aerial-survey/data visual register:
   restrained SaaS baseline (white, near-black ink, one blue accent) evolved
   with a second "aerial scan" cyan and an energetic price-tag coral for
   CTAs/pricing, plus motion (scan-line sweep, pulse, count-up) that reads
   as measurement/telemetry rather than decoration.

   No external fonts, no external requests. System font stack only.
