- Delete opportunity() JSON endpoint from api.py (dead after this refactor)
- Add GET /opportunity-map/data route returning HTML partial with two JSON
data islands (opp_points + ref_points from serving.location_profiles)
- Create partials/opportunity_map_data.html (2-line data island partial)
- Rewrite opportunity_map.html: HTMX attrs on <select>, invisible #map-data
swap target, htmx:afterSwap listener replaces fetch()-based loadCountry()
city_venues endpoint stays public (article-maps.js calls it on public pages).
