• See exactly what an upgrade does: every upgrade now shows a before→after preview (e.g. "Income $1.0K → $1.15K / task"), so you know the real effect before you buy.
• Smoother contracts: fixed an FPS drop that happened while a contract was on screen.
• Activity log stays put: switching themes no longer wipes your activity log.
• Delete Save now properly clears an active contract.

Thanks for the reports — keep 'em coming!
