Design a crisp exploded-view product illustration of a custom mechanical keyboard named LUMEN K65, shown in three-quarter perspective on a pale gray background with subtle shadow. Separate the layers clearly: keycaps, switches, plate, PCB, foam, gasket mounts, case top, battery module, rotary knob, and case bottom. Use anodized silver, matte black, translucent smoke keycaps, and small teal accent parts. Add clean technical callouts and in-image text reading "LUMEN K65", "Exploded Assembly", "65% Layout", "Hot-Swap PCB", and "3,200 mAh". Include labels for "PBT Keycaps", "Linear Switch", "Aluminum Plate", "Poron Foam", "USB-C", and "Encoder Knob". Show a compact dimension note "317 mm x 112 mm x 31 mm". The composition should feel like an industrial design presentation board: precise spacing, realistic materials, sharp typography, correct labels, and highly legible component hierarchy.

设计一张清晰锐利的爆炸视图产品插画，展示一款名为 LUMEN K65 的客制化机械键盘，以四分之三视角呈现，背景为浅灰色并带细微阴影。清晰分离各层：键帽、轴体、定位板、PCB、泡棉、gasket 垫片安装结构、上盖、电池模块、旋钮和底壳。使用阳极氧化银、哑光黑、半透明烟熏色键帽，以及少量青色点缀部件。添加干净的技术标注引线和画面内文字："LUMEN K65"、"Exploded Assembly"、"65% Layout"、"Hot-Swap PCB" 和 "3,200 mAh"。为 "PBT Keycaps"、"Linear Switch"、"Aluminum Plate"、"Poron Foam"、"USB-C" 和 "Encoder Knob" 添加标注。展示一个紧凑的尺寸说明 "317 mm x 112 mm x 31 mm"。整体构图应像一块工业设计提案板：间距精确、材质真实、字体锐利、标注正确，部件层级高度易读。
