Produce a design-system adoption plan for a product — tear down its bespoke UI, map every custom pattern to its design-system replacement, estimate the effort, and hand back a prioritized, phased build schedule. Use when the user wants to adopt, migrate to, or fully embrace a design system in an existing product, asks "what would it take to move this to our design system?", wants custom CSS replaced with system components, or asks for an adoption/migration plan or estimate. Companion to ds-inspection and product-inspection — the inspections find the warning lights; this produces the restoration estimate and build schedule.
