Tabs anatomy Chirp UI ships three tab-like contracts: tabs(...) and tab(...) from chirpui/tabs.html tabs_container(...), tab_button(...), and tab_panel(...) from chirpui/tabs_panels.html render_route_tabs(...) and route_tabs(...) from chirpui/route_tabs.html Route tabs are URL-backed navigation links with role="navigation" and aria-current="page". They are not ARIA tab widgets. Client-side tab panels use the chirpuiTabs() Alpine controller and escaped data-tab-id attributes. The full rendered contract, ARIA roles, htmx behavior, Alpine behavior, route tab semantics, and proof locations live in the canonical source guide: docs/components/tabs-anatomy.md.
