Explore HTML-to-blocks theme generation in Studio AI

[draganescu]

Context

This tracks a proof-of-concept workflow for turning an HTML/CSS design into editable WordPress blocks, then packaging the resulting workspace as a block theme from Studio AI.

What to validate

• Whether the html-to-blocks workspace model is the right abstraction for generated and imported designs.
• Whether the engine/tool split is fast enough for Studio's desktop agent path.
• Whether the visual comparison and completion gates are strict enough for final theme installation.
• Whether generated mockup creation should move out of generic file tools and into a dedicated workspace/engine primitive.

Current known risks

• Large generated designs can produce many model/tool turns through Write and Edit.
• Screenshot and visual-diff payloads can make sessions large.
• The engine currently runs as a child process per Studio tool call, so it does not benefit from a warm persistent harness.
