// CJS wrapper for Prettier to avoid dynamic import issues in Jest's VM.
|
|
// Prettier v3 has a CJS entry point but `await import('prettier')` in
|
|
// format-files.ts fails without --experimental-vm-modules.
|
|
// This wrapper loads the real module via require() so formatting actually runs.
|
|
//
|
|
// Prettier v3's index.cjs fires a top-level `import("./index.mjs")` which
|
|
// always fails in Jest's VM context. On Node v24+ the resulting unhandled
|
|
// rejection crashes the process. We collect any rejection promises that appear
|
|
// while loading prettier and mark them handled via .catch().

|
|
// by prettier's top-level import(). We .catch() them after loading to
|
|
// prevent Node from treating them as unhandled.
