// Single documented narrowing seam for "object used as an open
// string-keyed property bag" — the host global object and happy-dom's
// `Window` both genuinely ARE open records at runtime (we install /
// restore named globals like `window` / `document` on them by key),
// but TypeScript cannot express that without polluting the global type
// space via declaration merging. Centralizing the one structural
// widening here keeps every call site cast-free.

/**
 * View an object as an open string-keyed record.
 *
 * Single structural widening (`Record<string, unknown>` is assignable
 * to `object`, so the cast is checked in one direction by tsc — no
 * `unknown` erasure). Returns the SAME reference: property writes land
 * on the live object.
