Developer details pixel-perfect UI challenge for 372 test cards

A developer described a technical challenge involving the precise visual rendering of 372 digital practice test cards. The issue centered on a one-pixel rounding gap that became visible at a 3% zoom level. The problem was solved by applying a negative one-pixel inset to an image wrapper, allowing the image to overhang its container. This fix differed from a simpler scaling solution, which would have proportionally cropped content on a 373rd card type. The component was ultimately generalized to handle two distinct content formats with different layout requirements.
