  Renders the cart drawer (floating sidebar).

  The drawer slides in from the right when opened. It displays cart items
  and checkout options.

  ## Attributes

  * `cart_items` - List of cart items to display. Each item should have
    `image`, `name`, `variant`, and `price` keys. Default: []
  * `subtotal` - The subtotal to display. Default: nil (shows "£0.00")
  * `mode` - Either `:live` (default) for real stores or `:preview` for theme editor.
    In preview mode, "View basket" navigates via LiveView JS commands.

  ## Examples

  Renders a responsive `<picture>` element with AVIF, WebP, and JPEG sources.

  Computes available widths from `source_width` to avoid upscaling - only generates
  srcset entries for sizes smaller than or equal to the original image dimensions.

  The component renders:
  - `<source>` for AVIF (best compression, modern browsers)
  - `<source>` for WebP (good compression, broad support)
  - `<img>` with JPEG srcset (fallback for legacy browsers)

  ## Attributes

  * `src` - Required. Base path to the image variants (without size/extension).
  * `alt` - Required. Alt text for accessibility.
  * `source_width` - Required. Original image width in pixels.
  * `sizes` - Optional. Responsive sizes attribute. Defaults to "100vw".
  * `class` - Optional. CSS classes to apply to the `<img>` element.
  * `width` - Optional. Explicit width attribute.
  * `height` - Optional. Explicit height attribute.
  * `priority` - Optional. If true, sets eager loading and high fetchpriority.
    Defaults to false (lazy loading).

  ## Examples

      <.responsive_image
        src="/image_cache/abc123"
