The current shooting light in this city, translated into a photographer’s language. The sun is computed in your browser; the sky comes from Open-Meteo. Times are Stockholm’s, wherever you are.
Sightline reads the light before you leave the house. This page is its first public surface: the NOAA solar arithmetic that will drive the app, running live for one city. No backend, no account, no keys — if the weather feed fails, the sun stays correct, because the sun is math. The app itself — sun on real building geometry, to the minute, to the meter — is Study 02, coming 2026.
