mediadrop — Core (file intake) + Upload

mediadrop is a lightweight, headless-first file uploader for React. Core covers file selection, drag/drop, and validation via the useMediaDrop hook. Upload adds a real upload path on top: a pluggable transport contract, a queue with concurrency/retry/cancel, and a reference react-mediadrop/xhr-upload transport. Upload is opt-in — pass transport to get it; without it, nothing about Core's behavior changes at all. mediadrop is headless-first with no exceptions right now — there is no prebuilt widget/dashboard package; you own all markup.
