Build a shop navigation bar with Tailwind CSS: a top row with the logo, a wide product search field with a category dropdown inside it, and icons for account and cart; a second row with the main shop categories. Give the cart icon a badge showing the item count in the accent color, make the search dropdown filter categories as you type, and collapse the category row into a scrollable strip on mobile.
