stardust:dynamics — the dynamic surface of a migration

Static migration treats a page as content and layout. This skill treats it as behaviour: everything the source renders from JavaScript, a service or a data source, and everything the target host cannot serve the same way. Three real migrations found the same thing: the dynamic surface is invisible to a block-scoped, pixel-verified pipeline — and invisible in a way every gate certifies as correct. Modals rendered as links, video pills as CTAs without targets, a search box as a 404, forms that rendered and could not submit. This skill makes that surface visible and forces a decision per row before import, then proves the behaviour after delivery. It never blocks the static path; every page must still work as a static page.

When it runs — migration-bound, default-on there, never elsewhere
