Regulatory Rule Updating in the City: A gavel resting on an open book with gold-embossed pages, set against a blurred cityscape backdrop. The gavel, crafted from dark wood and featuring a gold band around its center, sits atop the book's pages, which are adorned with intricate golden patterns that evoke the appearance of lines of code or circuitry diagrams. The background, though out of focus, suggests a bustling urban environment at night, characterized by twinkling lights and an overall sense of activity.
