They share RawParserKit and disk-cache infrastructure, but they have deliberately different memory-admission rules.</p> <p>The key current invariant is: <strong>catalog preloading warms the 200 px grid cache and disk cache, but only UI demand may admit an image to the preview-size RAM cache</strong>. This keeps scan order from displacing the images the user is actively viewing.</p>
