Custom Responsive Gumroad Store Page

Build and publish a custom page for my Gumroad store (@shabraizalii). Design a unique, on-brand page — fully responsive, with light and dark mode. Preview it with `gumroad pages preview`, then publish with `gumroad pages push <slug>`. If I want an email signup, add a `<form data-gumroad-follow>` with an email input and an element marked `data-gumroad-follow-message` for the confirmation text — Gumroad wires the form to my email audience automatically.
