invalid built-in Dream Skin theme draft

Error message

invalid built-in Dream Skin theme draft

What it means

Guard in prepare_dream_skin_activation: a draft marked builtin must be exactly the default config with no custom image path; any deviation means the built-in theme was tampered with or corrupted, so activation is refused. The offending input is the draft being activated.
