## What it does

The skill points the agent at `\Hyva\Theme\ViewModel\Media` and builds a `getResponsivePictureHtml()` call from your data. You supply an array of image configs, attributes for the `<img>` tag (alt, class, loading, fetchpriority) and attributes for the `<picture>` wrapper. The agent then picks the right pattern: a single image with literal values, one pulled from a PHP variable, several images from an array, or separate sources behind media queries.

Loading strategy follows the image's role. A hero or any above-the-fold image gets `'loading' => 'eager'` with `'fetchpriority' => 'high'`; everything further down gets `'loading' => 'lazy'`. That split matters for LCP and CLS, so don't ask for lazy loading on the image that fills the first screen.

Have the file path inside `pub/media/` and its pixel dimensions ready before you start — the config can't be assembled without them. When the image comes from a PHP variable, the skill tells you which array shape it expects and points to `references/rendering-images.md`, where the full API reference lives.
