- Add 3-attempt retry with exponential backoff to Sreality, Realingo,
Bezrealitky, and PSN scrapers (CityHome and iDNES already had it)
- Add shared validate_listing() in scraper_stats.py; all 6 scrapers now
validate GPS bounds, price, area, and required fields before output
- Wire ratings to server /api/ratings on page load (merge with
localStorage) and save (async POST); ratings now persist across
browsers and devices
- Namespace JS hash IDs as {source}_{id} to prevent rating collisions
between listings from different portals with the same numeric ID
- Replace manual Czech diacritic table with unicodedata.normalize()
in merge_and_map.py for correct deduplication of all edge cases
- Correct README schedule docs: every 4 hours, not twice daily

Cover the full pipeline (scrapers, merge, map generation), all 6 data
sources with their parsing methods, filter criteria, CLI arguments,
Docker setup, caching, rate limiting, and project structure.
