## Key Capabilities & Data Dictionary

- **Real-Time Coordinates**: High-precision latitude/longitude with heading interpolation.
- **Delay Statuses**: Real-time delay minutes calculated against official published schedules (Green: on-time 0-5 min, Yellow: slight delay 6-15 min, Red: critical delay >15 min).
- **Hungarian Accent-Insensitive Search**: Full tokenization supporting queries with or without Hungarian diacritics (e.g. `gyor`, `nyiregyhaza`, `bekescsaba`).
- **PWA & Offline Capable**: Progressive Web App with Screen Wake Lock API and Web Share integration.
