# Minted Coin Hero

> Centered fintech hero with a raymarched coin rising from the bottom of the frame: raised rim, bead ring, an embossed planet emblem, lathe-turned field and a reeded edge, lit by a procedural studio of softboxes. Seven small coins tumble in orbit around it, it tilts toward the cursor, and it flips on a spring every few seconds or on click. The metal color is a prop. Raw WebGL, no three.js.
