(path: string)

// Derive a human-readable key from the file path, e.g.:
//   "./previews/modal-about.preview.tsx"  →  "modal-about"
function pathToKey(path: string): string {

// Build a map of key → lazy React component.
// Each preview file is expected to have a default export that is the preview component.
