- [x] Markets hub (`/<lang>/markets`) — article listing with FTS + country/region filters
- [x] DuckDB refresh script (`refresh_from_daas.py`)
- [x] **Opportunity Score integration**`opportunity_score` (Marktpotenzial) wired into city + country templates; `geoname_id` threaded through SQL chain (dim_cities → city_market_profile → pseo_city_costs_de); 71.4% city match rate; stats strip, intro paragraphs, market tables, and FAQ updated in both DE + EN
- [x] **Market Score v3 recalibration** — fixes ranking inversion (Germany 1/100k was outscoring Spain 36/100k); log-scaled density + count gate replaces linear formula; saturation discount removed; template thresholds updated across all 3 pSEO templates; verified: Málaga 70.1, Barcelona 67.4, Madrid 66.9, Amsterdam 58.4, Bernau 43.9 (was 92.7), Berlin 42.2, London 44.1
- [x] **Opportunity Score v2** — supply gap ceiling raised 4→8/100k (gentler gradient, accounts for 87% data undercount); formula documentation added (DuckDB LEAST NULL behaviour, income saturation, tennis data gap)

- [x] Overpass API extractor (OSM padel courts)
