+### Floorplan: photorealistic background via composite pipeline
+- **[HA]** Final "beautiful floorplan": Gemini one-shot render provided room interiors (good) with drifted geometry; a PIL compositor re-projected each room crop onto the exact plan geometry and redrew walls/doors/windows on top. Result deployed as `/local/floorplan-render.jpg`, set as Easy Floorplan floor `image` with `imageFit: stretch` (1:1 canvas mapping keeps the robot-tracker calibration). SVG furniture removed (backed up), areas made transparent, live device icons + tracker on top.
+- **[NOTE]** Reusable lesson: AI keeps either geometry or interiors, never both — composite (AI textures + coded geometry) is the deterministic path.
