Build a collapsible sidebar navigation with Tailwind CSS: a fixed-width vertical menu with grouped sections (each with a small heading), icon-plus-label items, and an active item highlighted with an accent background. Add a collapse toggle that shrinks the sidebar to icon-only width with tooltips on hover, and remembers the state. On mobile the sidebar becomes an off-canvas drawer with a backdrop.
