Native modal dialogs and nonmodal popovers with explicit ordinary alternatives.
Semantic page baseline
The route renders authored landmarks, headings, content, and ordinary destinations.
Overlays components
Dialog
A focused task in a native modal dialog. The rest of the page is inert while it is open.
Alert Dialog
A consequential confirmation with a native modal boundary and an explicit safe cancellation path.
Drawer
A native modal dialog presented at the logical start, end or bottom edge.
Popover
A native nonmodal surface beside an ordinary trigger, with a bounded centered placement fallback.
Dropdown Actions
Ordinary links and buttons grouped in an auto Popover. This is not an ARIA menu.
