Fixed a bunch of UI, animation, rendering, and performance issues across the Ethereal Light theme and the Settings Panel.
Real-time reasoning topic extraction now handles unfinished Markdown chunks correctly, so active words no longer get cut off while responses are streaming. I also switched to stable React keys, which eliminates the annoying text flickering during streaming.
The scrolling lock, content clipping, and hidden input issues in Ethereal Light have also been fixed by improving layer isolation and hardware acceleration.
Finally, repeated clicks on the Save button in Settings are now automatically deduplicated, preventing duplicate requests when the same configuration is submitted multiple times within 5 seconds.
