Showoff Saturday: I made a progressive-enhancement API for HDR web highlights

I wanted to see whether the extra brightness range on modern HDR displays could be useful for ordinary webpages, not just video.

The result is Brightpixels, a dependency-free library built around two custom elements:

```html <bright-text intensity="12">Important words</bright-text>

<bright-image intensity="8"> <img src="/photo.jpg" alt="Reflective metal" /> </bright-image> ```

On compatible setups it renders through an extended-range WebGPU canvas. Everywhere else, the original DOM text or image remains visible, so it works as progressive enhancement.

Text stays selectable, image alt text is preserved, and there's a React 19 entry with TypeScript declarations.

The project is at 0.1.0 and I'm looking for feedback on the API and device compatibility—particularly from people with HDR laptops and monitors.
