In this case, the file would be app/design/frontend/ExampleCorp/orange/Vendor_Module/layout/catalog_product_view.xml. The override directory is not used for overriding layout files, but for overriding templates and web assets.

The <your_theme_dir>/assets/images directory does not exist by default and is not used for storing favicons.

To customize the header of email templates, the developer needs to place the new template in the /Magento_Email/email/header.html path of the theme. This will override the default header template from the Magento_Email module. The /Magento_Email/templates/override/html/header.html path is not valid and will not work. The /Magento_Theme/html/header.html path is used for customizing the header of web pages, not emails.

To delete a manually installed theme, the developer needs to remove the theme directory from the app/design/frontend directory and also delete the corresponding record from the theme table in the database. The theme:uninstall CLI command is only used for deleting themes that are installed as Composer packages. Disabling the theme from the backend admin configuration does not delete the theme files or records, but only makes it unavailable for use.

To modify the width and height of all product images inside a theme, the developer needs to edit the view.xml file inside the etc directory of the theme.

The theme.xml file is used for specifying the parent theme and other metadata of the theme.

To move a block from one container to another, the developer needs to use the <move> layout instruction with the element attribute specifying the name of the block and the destination attribute specifying the name of the container. The after attribute can be used to position the block relative to other blocks in the same container. The value ''-'' means that the block will be placed after all other blocks, i.e., as the last child. The value ''last-child'' is not valid for the after attribute and will not work. The element and destination attributes should use the names of the blocks and containers, not their aliases or classes.

To register a new page layout in a custom theme, the developer needs to create a layouts.xml file in the app/design/frontend/<VendorName>/<ThemeName>/Magento_Theme/layout directory. The layouts.xml file should contain the <layout> element with the id, label, and file attributes. The id attribute is used to reference the layout in other layout files, the label attribute is used to display the layout name in the admin panel, and the file attribute is used to specify the path to the layout file relative to the web directory of the theme. The app/design/frontend/<VendorName>/<ThemeName>/layouts.xml and app/design/frontend/<VendorName>/<ThemeName>/Magento_Theme/layouts.xml files are not valid and will not work.
