Track all updates, improvements, and fixes to BasedScreenRecorder.Building in public, one release at a time.
Reduced live canvas compositing from 60 FPS to 30 FPS to lower CPU/GPU pressure when recording heavy browser tabs
Reduced real-time MP4 recording from 60 FPS to 30 FPS to improve stability and prevent lag buildup during long recordings

Download button in the share modal — download the processed video directly after sharing without closing the dialog
Shared videos failing to load on the watch page — COEP (require-corp) header was blocking R2 video URLs that don't carry Cross-Origin-Resource-Policy; header is now scoped to app routes only, excluding /watch/*
