** Enhanced Scanner Visuals
Upgraded the scanner radar with a denser, more cinematic interface.
Added layered radar grids, rotating scan lines, target rings, crosshairs, pulse effects, and green glow treatments.
Introduced ambient anomaly/glitch effects during active investigation sessions.
Improved the overall paranormal field-scanner atmosphere without obstructing core controls.
**Spectral Lock: Interactive Evidence Capture
Added Spectral Lock, a timed interactive signal-capture event available during active sessions.
Spectral targets appear at random positions on screen and can be tapped before they fade away.
A successful capture triggers a locking animation, visual LOCKED feedback, and native haptic feedback on supported devices.
Targets are positioned to avoid the End Session button and bottom navigation.
Spectral Lock pauses while a full-screen Rare Entity event is active, preventing interaction conflicts.
**Investigation Log Improvements
Successful Spectral Lock captures are now saved as persistent session evidence.
Each captured trace includes a themed signal description and an EMF reading.
Added a Captured Traces section to session cards in the Investigation Log.
Active and completed sessions can now display captured paranormal traces alongside readings, anomalies, messages, and peak EMF data.
**Rare Entity & Session Experience
Maintained the existing Rare Entity event flow, including its full-screen alert, countdown, session evidence logging, and sharing flow.
Improved the active-session experience with more visual activity and collectible evidence moments.
**App Store Review Prompt
Removed the custom in-app star-rating interface.
Added Apple’s native iOS App Store review prompt using expo-store-review.
The system review prompt is requested shortly after launch on supported iOS devices.
Apple controls whether and when the native review card is actually shown, according to its own frequency rules.
**Layout & Stability Improvements
Adjusted the main Scanner layout so the Start Session and End Session controls remain visible and tappable on compact mobile screens.
Added test identifiers to the new interactive controls for reliable automated testing.
Cleaned up a Reanimated render warning in the Spectral Lock component.
Verified the complete Spectral Lock flow: start session → capture target → view evidence in Sessions.
Confirmed TypeScript type checking passes successfully.
