/**
 * Returns a PascalCase identifier to name a component's default export binding,

 * `components`/`tags` directory) and the tag name normalizes to a valid
 * identifier. Otherwise `undefined`, so the extractor keeps a plain anonymous
 * `export default`. Naming the binding lets auto-imports read `import MyButton`
 * rather than TypeScript's file-derived `MyButtonMarko`.
