Throwaway OpenTUI (React) spike on Bun: 10k x 40 grid, every-field-type form, and a real
UI API process run with an async job against the qqq sample server. Records the go
decision, the measured latencies, binary sizes, and two server findings (bearer session
cannot continue an async process step under MOCK auth; url-encoded process values are
silently ignored). Adds scripts/dev launchers so the client can be tried after every step.
