Stepper component — mobile, brutalist style

Stepper UI component for websites and web apps, shown in Mintwell, a fictional finance product. Shows a five-step progress stepper with completed, current and upcoming steps, Back and Next buttons, and every step state (default, hover, focus-visible, current, disabled). 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: Stepper

Progress through a short multi-step task, with completed, current and upcoming steps and Back / Next buttons.

- **Pattern:** Semantic HTML (no ARIA widget role needed)
- **Roles and attributes:** An ordered list of steps; the current step has aria-current="step"; completed and upcoming states are spelled out in visually hidden text; a polite live region announces the step on Back / Next.
- **States drawn:** default, hover, focus-visible, selected, disabled
- **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:** reach Back and Next
- **Enter / Space:** go back or forward one step
