- New Settings > Data source toggle (Open-Meteo global / NWS US); NWS falls back to Open-Meteo when unavailable or outside its coverage. - src/lib/api/nws.js: /points -> forecast/hourly/grid normalizer producing the app's shared shape, with realistic air highs (NWS reports 104 for the day Open-Meteo over-forecasts at 116); heat-index/feels-like falls back to air temp since NWS returns apparentTemperature as null here. - NWS requires a User-Agent contact; email is a build-time Vite env (VITE_NWS_EMAIL), read from gitignored .env.local, never committed. - Details view now shows which provider served the data. - Fixes the identical UTC date-parse shift for NWS naive local times. - Tests (8) + recorded live fixtures for Rogers County, OK.
