Doesnt work for me on Firefox android. It asked for camera permission, then got stuck on validation. My camera works and was given permission.

i made a free website where blinking is used to go between pages because i hated having to pause playing the violin to press the arrow key/scroll to next page of pdf for piece im playing. i vibecoded this website and wanted to share it with others.

i literally made it cuz pausing my practice is annoying.
