App shell e navegação

Collapsible app sidebar with workspace switcher, nav groups and user menu.

App shell with a top nav, a sub-nav of pills, breadcrumbs, a page header and a ⌘K command palette that jumps to any page or action, plus notifications and an account menu.

Shell with a custom command palette (fuzzy search, groups, recent items, shortcuts, keyboard navigation) whose commands navigate, toggle dark mode and density, and open clients, with a log of what happened.

Responsive shell: sidebar on desktop, animated bottom tabs with badges on mobile, a floating action button and a bottom-sheet booking form that validates and adds to today's list.

Page header patterns in one scrolling page: breadcrumb, avatar, inline rename, status badge, primary and overflow actions, tabs with counts, filter chips, a delete confirmation, and a sticky header that compacts on scroll.

Master-detail inbox with a drag-to-resize divider that also works with the keyboard, unread and starred threads, j/k navigation, replies that post to the thread, archive with undo and a stacked mobile layout with back.

Shell with a bell that wiggles and counts, per-page badges in the sidebar, a notification drawer with all/unread filter, inline accept/decline, dismiss, mark all read, do-not-disturb and a simulate button.
