Breadcrumbs component — mobile, brutalist style

Breadcrumbs UI component for websites and web apps, shown in Juniper Supply, a fictional commerce product. Shows a full breadcrumb trail with the current page, a long trail collapsed behind a show-more button, a mobile back-to-parent form, and every link state (default, hover, focus-visible, current, collapsed). Brutalist style: high contrast, Space Grotesk, uppercase headings, thick black borders and hard offset shadows. Comes with copyable HTML, CSS and a few lines of plain JavaScript (keyboard support and ARIA per the WAI-ARIA Authoring Practices), a live demo, and a DESIGN.md with light and dark colour tokens.

Component section (states, ARIA, keyboard)

## Component: Breadcrumbs

Where the current page sits in the site. On narrow screens the middle levels fold into a back link to the parent.

- **Pattern:** WAI-ARIA Authoring Practices, Breadcrumb (https://www.w3.org/WAI/ARIA/apg/patterns/breadcrumb/)
- **Roles and attributes:** <nav aria-label="Breadcrumb"> around an ordered list of links; the last item is the current page with aria-current="page"; separators are drawn with CSS so screen readers do not read them.
- **States drawn:** default, hover, focus-visible, current, collapsed
- **Focus:** a visible `:focus-visible` outline (3px solid text), never removed
- **Style knobs (brutalist):** border 2px, corners 0, shadow `3px 3px 0 var(--text)`, labels uppercase, tracked .02em
- **Motion:** transitions are short (≤160ms) and switched off under `prefers-reduced-motion: reduce`
- **Code:** HTML + CSS + a few lines of plain JavaScript (no libraries); colours come only from the tokens above, so light and dark both work

### Keyboard
- **Tab:** move between the links
- **Enter:** follow a link
