Holographic Member Pass
A founding-member pass with real holographic foil: tilt it with the pointer and a rainbow band slides across the card while a glare follows your hand and tiny sparkles catch the light; type your name beside it and it is engraved onto the pass as you type.
The mechanic
Rainbow foil = `repeating-linear-gradient(115deg, …7 hues…)` at 300 % size with `background-position: calc(var(--mx) * 1%) 50%` and `mix-blend-mode: color-dodge`, so the bands slide opposite to the tilt like real diffraction foil; sparkles only appear inside a mask circle at the light position.
