Build a dashboard app shell with Tailwind CSS: a fixed sidebar with grouped navigation (icons plus labels, active item highlighted), a top bar with page title, search and account menu, and a main area whose first row is four stat cards followed by a content panel. Keep the sidebar collapsible to icons, make the stat row responsive to two-by-two, and give the whole shell a consistent max width for the content column.
