Breadcrumb

The path from the top of the app to the current page: Projects, Werewolf, Settings. Each ancestor is a link in secondary text; the current page is primary text, not a link. A caret sits between them.

Cấu tạo

Phần	Mô tả
root	Breadcrumb: a nav named Breadcrumb.
list	BreadcrumbList: the steps in a row that wraps, 13px secondary text, gap-sm.
item	BreadcrumbItem: one step.
link	BreadcrumbLink: an ancestor, a link in secondary text that turns primary and underlined on hover. asChild takes the app's own link component.
current	BreadcrumbPage: the current page in primary text, aria-current="page".
separator	BreadcrumbSeparator: a Tabler ChevronRight, 16px, secondary; pass children for another mark.
ellipsis	BreadcrumbEllipsis: Tabler Dots, 16px, for the steps left out of a long path.

Role: navigation

Phím	Hành động
Tab	Moves through the links; the current page and the carets are not focusable.

The nav is named Breadcrumb, so screen readers list it with the page's landmarks. Pass aria-label to rename it.
The steps are an ordered list. The current page carries aria-current="page".
The carets and the ellipsis are decorative and hidden from screen readers. A collapsed path goes in a DropdownMenu whose trigger is named, such as Show the full path.
The caret turns around in a right-to-left page.

Lệnh này thêm luôn styles/werewolf.css, bộ token mà mọi component dùng, và các component khác mà nó cần. Import file đó một lần trong CSS gốc, ngay sau @import "tailwindcss", với đường dẫn tính từ file CSS đó (từ app/globals.css là @import "../styles/werewolf.css").
