Aldus 1.28.0

• Cover and group block serialization matches WordPress core more closely — fewer “unexpected or invalid content” warnings after you pick a layout (especially when your theme sets a custom cover overlay color).
• Assemble responses are easier for the editor to use: prefer server block markup when inserting layouts so previews match what PHP generated.
• Headings with a theme font preset include the correct font-family class in saved HTML alongside block attributes.
