Demo

Several UI readability fixes added, including clearer detection status, simpler O2/electricity readouts, and a more readable pause overlay.
Detection behavior was refined around periscope depth, decks-awash state, and the first moment after raising the periscope.
Disengagement is now available when all remaining enemies are confirmed sinking
Tactical tip for when all enemies are confirmed sinking
Map plotting tools now snap more reliably to ownship and revealed ships, including when re-positioning elements.

Campaign Improvements (Playtesters only)

Campaign radio equipment now improves over time through historical radio upgrade events. Radio upgrades become available after returning to port.
Radio sending / receiving improved: sending messages moved entire to sending tab, also added "Ascend and send" vs "Send when able" buttons
Save/load screens now separate campaign saves from scenario saves, making it harder to load the wrong type.
Radio contacts are now less noisy and can automatically pause the game when new contact reports arrive.
Hydrophone sweeps on the patrol map now show a clear blue sweep cone around the submarine.
Radio reports can now be queued while too deep: either surface and send automatically, or send when radio depth is reached.
Improved radio report UI arrows
Tactical guidance now appears when an encounter can be engaged
