If I may indulge in some silly OCD feedback: the hero animation with pages turning has the shadow on the top right line up with the corner, which makes it as if the device has an inset chamfered bezel, which I feel is of disservice to the device. That tripped me up hard until I looked at the other side where the shadow is hitting halfway.

Anyway, congratulations! I both hope you succeed and that it helps drag the 60Hz eink needle forward across the industry.
