/**
 * Initialises the statics root from the directory of the package entry point.
 * Must be called before any test fixture helpers are invoked.
 *
 * The package entry points (index.ts for ESM, index.cts for CJS) call this
 * with their own `path.dirname(fileURLToPath(import.meta.url))` or `__dirname`
 * respectively, so this module contains no module-system-specific syntax and
 * compiles correctly under both `module: NodeNext` and `module: CommonJS`.
 *
 * Design note — eager-init vs lazy resolution:
 * An alternative would be to resolve the statics path lazily inside
 * getStaticFilePath() on first call (eliminating _initStaticsRoot and the
 * entry-point coupling entirely).  Eager-init was chosen instead because lazy
 * resolution cannot safely use import.meta.url in a CommonJS build, and
 * __dirname is not available in an ESM build.  The entry-point side-effect
 * approach lets this module stay free of module-system-specific syntax while
 * still capturing the correct anchor directory at load time.
