This 3 x 3 in kiss-cut sticker puts the optimistic email regex on a clean square layout that reads well on laptops and desk gear. It is a good fit for developers who know the pattern is useful, flawed, and still somehow in production.
Light mode edition for bright desks, clean contrast, and daytime debugging.
Dimensions: 3 x 3 in (76 x 76 mm), kiss-cut sticker.
