Create the .pixl workspace in the current project, boot the local browser preview, and open it. Call this first. Returns the preview URL to relay to the user.

Report current workspace state: whether initialized, the active design system, screen count, flow node count, and preview URL.

List the curated design-system presets. Show these to the user and let them pick one (by id) before calling pixl_set_design_system.

Lock the design system. Pass a presetId (from pixl_list_presets) with optional overrides, OR fully custom tokens. Writes tokens.json + design/*.md and returns the TOKEN CONTRACT — obey it for every screen you generate.

Record the screen list and the user journey between them. Writes screens.md and seeds the flow map. Do this after the design system is set and before generating screens.

Submit a screen's HTML. It is linted against the token contract; on pass it is saved to screens/.html and live-renders in the gallery, on fail the violations are returned and NOTHING is saved — fix them and resubmit.

Lint provided HTML against the active token contract WITHOUT saving. Use to check a draft before committing it with pixl_write_screen.

Set/update the user-journey graph the flow canvas renders. Provide the edges (transitions between screen ids). Nodes default to one per planned screen and keep any positions the user has dragged. Writes flow.json and live-updates the Flow tab.
