Base UI Desk - a Radix UI file moved to Base UI

Move one Radix UI file - a shadcn ui wrapper, a page that uses the wrappers, or a hand-rolled composition - to Base UI. Free in your browser: both Radix import forms rewritten to one @base-ui/react subpath, the part renames (Overlay to Backdrop, Content to Popup or Panel, tabs Trigger to Tab, menu Label to GroupLabel, select Viewport to List, slider Range to Indicator), positioned popups to Portal > Positioner > Popup, asChild to render, Part.Props types, the data-state selectors and --radix variables, and the 1:1 call-site props - with the animation idiom, dismiss callbacks, missing parts and behavior changes flagged and cmdk, vaul and sonner left alone, plus the checklist, the steps and CSVs. Metered runs write the review (each finding decided, what a scan cannot see, the order, the behavior changes and the hand checks - the .migration report) and the whole -base file, which the page re-scans. Built on the SkillSafe skill @shadcn/migrate-radix-to-base, from shadcn-ui/ui (MIT). An independent tool - not affiliated with or endorsed by Base UI, MUI, Radix UI, WorkOS or shadcn/ui.
