-Fixed a bug that allowed users to get 6 free scans instead of 3 by signing up after using guest scans — guests now get 1 free scan, with 2 more after creating an account (3 lifetime total)
-Added a welcome screen for new users after account creation
-Experiments and cross-mode projects are now sorted to the bottom of each mode list so mode-exclusive content appears first
-My Lab data (active projects, journal entries, check-ins) syncs to the server and persists across devices
-Fixed App Store description
