Matte Button

A matte chip button with a holographic rim: three blurred glows pinned under the top edge, a bounce light along the bottom, and a gradient-clipped label and mask-painted icon. Four shadcn sizes with the corner curvature held constant, an expo-out hover that lifts the chip and pushes the ink, and a light theme that is the same layer stack with swapped tokens and a multiplied rim. Every custom property is defined on the button, so it needs nothing from the host stylesheet.
