# Coldspar — Hardware Wallet Landing with a CSS-3D Device

## What you're building

A dark product landing for **Coldspar CX-1**, a fictional self-custody hardware wallet. The hero's right column holds the device itself — a real CSS 3D object (`transform-style: preserve-3d`, six faces, a milled edge band) that tilts toward the pointer with damped, clamped rotation, while a specular sweep and a contact shadow both track the tilt. The distinctive technique is that this is pure CSS transforms and gradients: no WebGL, no model file, no image of a product.

Coldspar is an invented brand. Every figure, spec and claim on the page is placeholder content, and the page says so twice — in the specs caption and in the footer disclaimer.
