### Before you start - [x] I searched the [existing issues](https://github.com/opengeos/GeoLibre/issues) and did not find a duplicate. - [x] This is a bug report, not a usage question (questions belong in [Discussions](https://github.com/opengeos/GeoLibre/discussions)). ### What happened? When a user opens a project via the gallery link, the plugin panels are open and blocking the view. <img width="776" height="680" alt="Image" src="https://github.com/user-attachments/assets/e932a166-3fcd-47e0-8cce-c9ecbd353fe2" /> ### Steps to reproduce Visit https://web.geolibre.app/?url=https://share.geolibre.app/spatialthoughts/maritime-piracy.geolibre.json ### Expected behavior Basemap panel should be hidden ### How are you running GeoLibre?
