Local-first prototype skill

Fast ideas.
Owned folders.

Picker for live visual variants. Dated owners for real prototypes. Compare two options. Package a static ZIP. No experiment orchestra.

01owner per artifact
00external runtime
ZIPstatic pack
3picker variants, default

Picker, quick, compare, ship.

Live visual variants stay in the page. Dated work lives at prototypes/YYYY/MM/NNN-slug/. Verify is self-containment, not a four-viewport receipt machine.

The refusal

No proof laundering.
No variant soup.

A compare page can switch artifacts; it does not own their runtime. A package can carry files; it does not turn a draft into a production claim.
