plan_scene

PLAN (read-only, no mutation) — the UNDERSTAND + PLAN step for any medium or complex request. Pass theme (free text, e.g. 'a backyard picnic with burgers and cake'), optional type (an archetype id: backyard_picnic|graveyard|market|house|castle|forest_camp|harbor|arcade|village|street|skate_park|arena|farm|park), optional seed (same theme + same seed = the same plan; omit to mint a fresh world). Returns the intent (scene type, story, focal point, required and supporting elements, complexity), the zone program (which places, where, why), the environment (theme, ground, boundary), circulation, the seeded composition summary per zone, and next — the exact call sequence to build it. Nothing is placed and nothing on the canvas changes: read the plan, adjust if you must (create_zone, apply_theme after composing), then call compose_scene with the plan_id. Do NOT call this for a small addition.
