Research direction

Open the linked CodeSandbox and reproduce the hang with @mui/material, @emotion/react, @emotion/styled, and @mui/icons-material. Start from the CodeSandbox transpilation/loading path; done means a fresh project with these packages loads instead of remaining on “Transpiling Modules” or showing a white screen.
