Build a welcome tour modal with Tailwind CSS: a first-run dialog with a short welcome line, three things to try as small rows (each with an icon and a one-line description), a primary 'start the tour' button and a secondary 'explore on my own' link. Trap focus while open, close on Escape or backdrop, show it only once per account, and make sure the three items match what the product actually wants people to do first.
