List all available illustration styles.

Style is what keeps a set of illustrations looking like one family. Pick one style and pass its pretty_id to search_illustrations for every illustration in a project, the way you would keep to a single icon platform.

Args: ctx: MCP context for API access limit: Styles per page (default: 50) page: Page number, 1-based (default: 1) free_only: Only styles whose illustrations a free Icons8 account can use and redistribute. A style without this flag needs a paid account - the ordinary case for a subscriber, not a style this user is barred from animated: True for animated styles only, False for static only. THIS IS A PROPERTY OF THE STYLE, NOT A COUNT. It says the style has video and animation formats at all - it does not say how many of its illustrations actually move, and usually very few do: measured on stage, 3d-business carries the flag with 19 animated illustrations out of 1497, flexy 15 out of 561, and node carries it with none at all yet. So use it to browse styles, and use search_illustrations(animated=True) to find illustrations that move - that one filters on media_types, which is the per-illustration answer

Returns: {"total", "styles"} where each style has pretty_id, title, illustrations_count, free_distribution and animated - or {"error"}
