# Progress Pulse

> A soft, organic upload progress bar whose gradient, typography, card shape, elevation, surfaces and light/dark themes follow the active design system. The fill breathes with a gentle opacity pulse and animates only opacity and transform.

## Features

- A single soft, rounded determinate progress bar with a design-system gradient fill
- A calm opacity pulse that makes the fill breathe (opacity keyframe only — no layout thrash)
- Static upload progress seeded from `data-progress`, with no fake increment/decrement controls
- Determinate fill sized from a `data-progress` seed and animated with a transform `scaleX` transition (never a width transition)
- `role="progressbar"` with synchronized `aria-valuenow`, `aria-valuetext` and an accessible task label
- Both the task label and visible percentage use the theme's guaranteed primary foreground; accents remain concentrated in the fill and ambient blooms
- Asymmetric radial blooms and a tinted card whose radius and elevation propagate from the active design system
- Reduced-motion support that stops the pulse and neutralizes the transform transition

## Accessibility

- **ARIA role** — The bar uses `role="progressbar"` with `aria-valuenow`/`aria-valuemin`/`aria-valuemax`
- **Accessible name** — The card and progress bar reference the visible `<h1>` task label through `aria-labelledby`
- **Value semantics** — `pbApplyProgress()` synchronises the authored value, readout, `aria-valuenow` and `aria-valuetext` on load
- **Decorative value** — The visible percentage carries `aria-hidden="true"` and stays in sync with the bar's aria state
- **Focus indicators** — `:focus-visible` with `--ring` outline
- **Reduced motion** — `prefers-reduced-motion: reduce` stops the pulse and neutralizes transitions
- **Viewport** — `100dvh` for mobile-safe viewport height
