    Contract

    Semantics first

    Anatomy

    Uses nav, unordered list, anchors, and aria-current=page; disabled entries are non-link text.

    Consumer classes, styles, and data attributes may extend the surface, but required roles, IDs, relationships, and handlers remain owned by the component.

    Keyboard

    • Tab reaches enabled links in order.
    • Enter follows the focused destination.
    • Disabled entries are not focusable.

    Known issues

    • TopNav does not collapse or provide overflow behavior; the caller must preserve every destination at narrow widths.

    Version & provenance

    New in the v2 architecture

    There is no stable predecessor for this explicit compiled subpath. The v1 compatibility layer remains tested separately; visual and API diffs begin with the next prerelease.
