What

The artifact-design skill is now loaded before writing any artifact, including plain Markdown ones, rather than only HTML. It adds rules for the viewer's three theme states, for titling, and for steering away from design defaults that read as obviously AI-generated.

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
