Fixes based on your reviews.
• Paid filters (Seoul · Tokyo · Taipei · B&W) now show a lock. Preview is free; saving and sharing need City Pack.
• Video and burst now tell you before you shoot — nothing you capture gets thrown away anymore.
• Cancelling a share keeps your photo on screen.
• Recording survives notifications and Control Center, and saves automatically if you leave the app. Microphone permission is asked before recording starts.
• Landscape videos are saved in landscape.
• In video mode the flash button works as a light (torch).
• Clear messages when a save fails or permission is denied, plus a burst summary.
• The default filter level in Settings applies immediately. Added camera tips.
• Other stability improvements.
