list_fonts

List font families available in the active project — Creator's curated presets, Google Fonts, OS-installed local fonts (when permission has been granted), and project-uploaded font assets. Use this when the user names a specific font you're not sure is loaded ('animate "Acme" in Bebas Neue letter-by-letter'), or when you need to recommend a fallback that's actually present. When to call: - User names a font you're not certain exists in this project (brand fonts, niche typefaces). - You're about to call `create_text` / `set_text_style` with a specific `font_name` and want to verify the family + style are loaded. - You're deciding between multiple style options for the same family. When NOT to call: - The user didn't specify a font — `create_text` uses the project default. Calling this would just burn a turn. - You already called it earlier in the conversation. Returns `{ families: [{ family, styles, default_style, source }] }`. `source` is one of `'PRESET' | 'GOOGLE_FONT' | 'LOCAL' | 'ASSET'`. If the requested family isn't in the list, fall back to a similar style + tell the user (e.g. 'Bebas Neue isn't loaded; I used Anton, the closest condensed sans available'). Pass `source` to filter to one category. Note: the catalog is a snapshot of what's currently loaded. Local OS fonts only appear after the user grants the browser's `local-fonts` permission, which Creator does not prompt for automatically.
