-/**
- * Shared steps for the two `pdfjs-one-runtime-*` files (GitHub #1277).
- *
- * Under Node, pdf.js runs its worker in-process and keeps it on
- * `globalThis.pdfjsWorker`. Whichever pdf.js copy opens a document first
- * owns that global for the life of the process, and a different copy then
- * refuses every document with "The API version … does not match the Worker
- * version …". The text reader and the rasterizer once loaded different
- * copies, so whichever ran first broke the other until a restart.
- *
- * Each order needs a fresh process, because the global cannot be taken back
- * once claimed; that is why the two orders live in two files (the isolated
- * project gives each file its own process) instead of two tests here.
