1. Production Architecture: Instant Tag-Based Edge Invalidation & `stale-while-revalidate` Header Architecture

def set_edge_cache_headers(response, cache_tags: list[str], s_maxage: int = 300, swr: int = 86400):
    response["Cache-Control"] = f"public, max-age=0, s-maxage={s_maxage}, stale-while-revalidate={swr}"
    response["Cache-Tag"] = ",".join(cache_tags)
    return response
