Thank you so much! A genuinely silly amount of time went into the website.

If you'll indulge me for a moment, because I never get to talk about this stuff: the corner radii of the cards on the site are actually "squircles" rather than perfect rounded corners. To me this is much more pleasing to the eye. The squircles are achieved by creating a PNG mask which is then 9-sliced and expanded to mask off the edge of the cards. Another mask is used for the stroke and laid on top of the first mask, to give the gradient border effect.
