Neutralize Amazon’s product video dimming overlay in Safari so playback brightness stays constant when controls appear.
Keeps Amazon product videos watchable in Safari by stripping out every dimming overlay that darkens the playback area when UI controls appear. Injects a persistent style patch and mutation observer to neutralize overlays, force video brightness back to 1, remove dim-video-player effects, and keep the control bar transparent. Works on product pages and full-screen playback so the picture stays bright and stable. Suggested follow-up: test on a few product videos to confirm no new overlays slipped through.
