A keyboard- and screen-reader-friendly breadcrumb. The `aria-label="Breadcrumb"` on `<nav>` announces the role; `aria-current="page"` marks the final segment. Add the JSON-LD for Google's rich result.
Use `<nav>` for primary navigation. Mark the currently-active link with `aria-current="page"` — screen readers will announce it, and you get a free CSS hook with `[aria-current]`.
Standard site footer with grouped links, brand block, social icons, and legal/copyright. Use semantic `<nav aria-label>` on each column so screen readers announce the section labels.
