  Next.js 16's build hangs when a web worker imports the module that starts it

  What happened

  next build (Turbopack) hung and had to be killed: the worker imported infall-geodesics.ts, which started the worker that imported it.

  The fix

  the code that starts the worker lives in a module of its own (infall-tables.ts) that the worker never imports.

• My own mistake/L-WJHHAI

  A server page that imports a plain object from a 'use client' module gets a reference, not the object

  What happened

  the page received a client reference, and every field of the object read as undefined.

  The fix

  data shared by server and client lives in a plain module, without "use client" (infall-hero-data.ts).
