Vaultline Armored Vault Crypto Hero

Full-viewport navy hero for a fictional crypto wallet: a riveted gunmetal vault sphere rises from the bottom edge, its seams leaking electric-blue and mint light in a feathered square video loop over the still artwork. Above it sit a trust badge, an avatar stack, a two-line metallic-gradient uppercase headline and a blue-to-mint CTA, with four glowing icon features framing the sphere. Plain HTML, CSS and vanilla JS with a Web Animations entrance, scaling from a 2048px frame to a stacked 2x2 phone layout.
