`fx_studio_open`

Open FX Studio

Opens the live FX Studio creative workbench, optionally on a saved scene. The same view updates as its actual HTML/CSS/JavaScript source changes through scene_read, scene_write or scene_edit and as scene_preview renders images. Supports DOM, SVG, Canvas and WebGL through one programmable scene contract. Opening is read-only and does not create an effect or change production defaults. Returns a first-party studio link for hosts without app rendering. The view stays current through successive edits; only this tool opens the app.
