• Introduced category-based consent (Essential, Analytics, Marketing) with a single banner and settings screen.

🔄 Improvements

• Faster privacy page loading by caching policy versions on startup.
• Improved transcription branch text handling to better preserve your edits and map text more accurately.

🛠 Fixes
