Core Magento Compatibility Modules

When developing compatibility modules for Magento (e.g., Adobe Commerce or B2B), the Hyvä reset theme removes all original module layout XML declarations.

For example, the `Magento_Banner` module's `default.xml` layout XML blocks are removed as shown:

<referenceContainer name="content">
    <!--
        <block
            name="banner.data"
            class="Magento\Banner\Block\Ajax\Data"
            template="Magento_Banner::js/banner.phtml"
        />
    -->
</referenceContainer>

Hyvä is a new theme, built from scratch, not based on Luma. The commented-out blocks serve as a reference to the original structure. Hyvä aims to maintain all containers and extension points.

To resolve this, create a `hyva_default.xml` layout file within your compatibility module and re-add the necessary blocks.
