### Floorplan: photorealistic background v3 — per-room Gemini API generation (final)
- **[HA]** Winning pipeline: each room generated INDIVIDUALLY via `gemini-3.1-flash-image` REST API (billing key; room photos inline + per-room aspectRatio) — single rectangular room = trivial geometry, so both furniture and framing are accurate. PIL composite (5.5% edge crop, resize to area bboxes, walls/doors/windows drawn on top) → `/local/floorplan-render.jpg?v=3` (cache-bust required). Room renders archived in Obsidian for one-room re-generation later. ~$0.50 total.

- **[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. - **[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.

- **[NOTE]** Reusable lesson: AI keeps either geometry or interiors, never both — composite (AI textures + coded geometry) is the deterministic path. - **[NOTE]** Reusable lesson: AI keeps either geometry or interiors, never both — composite (AI textures + coded geometry) is the deterministic path.
