The prompt

Build a first-run welcome modal with Tailwind CSS. Use a fixed inset-0 overlay with a blurred dark backdrop centring a max-w-lg white card with rounded-2xl corners. The card opens with a wide banner area drawn as a soft neutral gradient holding a large glyph and a small monospaced version tag in the corner. Under it, a heading welcoming the person by name, a paragraph of two sentences, and three suggested actions as bordered rows with a glyph tile, a title, a one-line description and a right chevron, the first row carrying a small "Start here" pill. The footer has a checkbox reading "Do not show this again" on the left and two buttons on the right, a ghost "Skip the tour" and a dark "Take the tour". Then add JavaScript that closes the modal on either button, on Escape and on a backdrop click, and remembers the checkbox choice in localStorage so a return visit skips it.

Paste it into Claude, Cursor, v0 or any AI coding tool. Prefer the finished markup? Open the Tailwind source.
