## Editor-Test (headless): Karte t_f72913d4 — Atmosphäre & Skybox.
## Ausführen: godot --headless --path . --script res://tests/test_skybox.gd
## Exit 0 = alles grün.
##
##   T1  svmap-Validierung (V17): weather_sky optional; "sky_panorama"/
##       "prozedural" gültig, Quatsch/nicht-String → V17-Fehler; alte Karte
##       ohne Feld validiert unverändert.
##   T2  Map-Panel „Himmel“: doc-Roundtrip (schreiben = sky_panorama,
##       „Standard“ = Feld ENTFERNEN, Auffüllen aus dem doc).
##   T3  Editor-Vorschau (map_view_builder): weather_sky=sky_panorama →
##       PanoramaSkyMaterial aus dem Client-Nachbar-Klon + ACES-Tonemap +
##       Fog am Skybox-Horizont; ohne Feld → ProceduralSky (alte Maps
##       unverändert).
