Bug fixes and reliability improvements. The Upgrade to Pro button in the AI Assistant now opens the subscription screen, and Pro subscribers no longer see the free-limit message. The assistant button returns after starting the app offline. Sharing from a rock page always uses the rock you are viewing. The offline Crystals list keeps every mineral. Also fixes upscaled thin-section frames, marker editing, the turntable, and subscription status.

Marker display is now controlled with two simple switches in the viewer settings: Official markers and My Markers (Pro). Your choices are remembered across launches. Upgrading from 1.1.1 or earlier also brings the crystal structure rendering fixes and the offline Crystals tab fix.

Crystal structure fixes: ionic bonds now render correctly (for example halite), mixed-site atoms display at occupancy-proportional sizes, and the unit-cell box is hidden for a cleaner view. Also fixed the Crystals tab failing to load when the app starts offline.
