Navigation
Rails, switchers, and slide-ins that hold context on every screen size.
The rail
Sidebar is the app chrome: Provider owns the collapse state, Header holds the ProjectSwitcher, Content stacks labeled groups of menu buttons, and the Trigger toggles the whole rail. Below the md breakpoint the same rail re-renders as a slide-in Sheet.
Project switcher
Grouped accounts then projects, a checkmark on the current id, and an optional Create project action.
Current: founding-eng
Slide-in and mobile
Below the desktop breakpoint, navigation lives behind a trigger and slides in from the left as a Sheet with the same list. This book's own top bar on small screens is this pattern, live.
Wayfinding
Where am I, and where can I go: Breadcrumb states the path, Tabs switch peer views, and LinkMenu holds the external profiles behind one trigger.
