Vault

Build a full-viewport, single-screen cinematic hero for a self-custody crypto wallet called VAULT. One self-contained HTML file: inline <style>, inline <script> (only if needed), Google Fonts via <link> in the head, no build step, no external assets except the fonts and one background video. The whole page is a single 100vh/100dvh hero — no scrolling, no extra sections. It must render perfectly at 1280x800 (it will be screen-recorded at that size). THEME: DARK. Archetype: centered minimal, product-forward. Calm, confident, high-end — not busy, not sci-fi.
