内置image_gen编辑，原始V7田间渲染为参考。

Use case: precise-object-edit.
Edit the reference V7 field photo. Preserve the entire scene, camera angle, original V7 product geometry, pole and metal mounting straps EXACTLY. V7 is the TALL golden-ratio version: housing height 161.8 mm, width 100 mm, depth 28 mm, front H/W=1.618. Tall narrow warm-white rounded front, dark rectangular solar panel, orange rear, tiny LEDs and 1/2 buttons, exactly TWO bottom-facing gray electrical cable connectors with two cables, two steel bands holding original back mounting bosses to a galvanized round pole. NO square V6/V8 body, NO single rear connector, NO white central holder. Do not redesign or stretch product independently from the reference.
Change ONLY: remove the two small lines of white Chinese caption at bottom left ('田间安装效果' and 'V7 外观概念'), filling with natural continuity of existing plants/soil. Remove no hardware or field details. No other text, no new badges, no 4G label. Keep landscape 3:2 composition, premium realistic morning field photography, same product position and same golden-ratio shape.
