"""Bild-Optimierer für GeoGraSim.
|
|
|
|
Bewegt Originale in `_original/`-Unterordner, generiert daneben WebP-Variante
|
|
in der jeweiligen Zielbreite. Höhe wird proportional skaliert.

|
Konvention:
|
|
vorher: foo/bar.png (groß, PNG)
|
|
nachher: foo/_original/bar.png (Backup, NICHT im Deploy)
|
|
foo/bar.webp (deploy-ready, klein)
