## Features

- A single gradient determinate progress bar inside a split-tone card
- Orange-to-amber gradient fill built from `--pb-grad-start`/`--pb-grad-end` tokens
- A soft light sheen sweeps across the fill via a `transform: translateX` pseudo-element
- Fill length driven by a `--pb-prog` custom property, animated with a `clip-path` reveal so the sheen never distorts
- Static upload progress authored through `aria-valuenow`, with no fake increment/decrement controls
- Gradient-clipped percent readout that stays in sync with the bar and its `aria-valuenow`
- Split-tone panel: a brand-tinted header band over a plain surface body, split by a hairline divider
- A soft diagonal sunset-wash backdrop built from the gradient tokens, with a designed dark twin
- `role="progressbar"` with an authored `aria-valuenow` and explicit bounds
- Reduced-motion support that stops the sheen, entrance and step animations

## Accessibility

- **ARIA roles** — Bar uses `role="progressbar"` with `aria-valuenow`/`aria-valuemin`/`aria-valuemax`
- **Value semantics** — The initial script synchronises the authored value, readout and `aria-label` on load
- **Focus indicators** — `:focus-visible` with `--ring` outline
- **Reduced motion** — `prefers-reduced-motion: reduce` stops the sheen, entrance and step animations
- **Viewport** — `100dvh` for mobile-safe viewport height
