The prompt

Create a demo booking panel with Tailwind CSS: a left column with the host avatar, host name and role, the meeting length with a clock glyph, the timezone, and three bullet points about what the call covers. A right column shows a horizontal row of selectable day chips (weekday abbreviation over the date number) with one selected in dark, then a grid of time-slot buttons where one is disabled, and a full-width confirm button below. Stack the columns on mobile. Then add JavaScript that makes the picker behave: selecting a day highlights it and loads that day's slots — each day offers different availability, and a day with none shows a "fully booked" message — selecting a slot highlights it and clears when the day changes, and the confirm button stays disabled until both are chosen, then names the exact day and time it will book.
