• intros：{"brand_intro":"乐圣成立于2008年，由古琴修复师张乐圣创立，专攻高端定制琴轸与琴穗。品牌以\"一轸一世界\"为理念，每枚琴轸均采用明清老料（拆房老料或古船木），并嵌入0.3mm银丝勾勒祥云纹。张乐圣曾为多位国家级非遗传承人制作琴轸，年产量仅200套，被誉为\"琴轸界的爱马仕\"。","product_intro":"此款琴轸定位收藏级，选用明代老房梁檀木（经碳14检测），密度高达1.3g/cm³，音色传导速度比新料快15%。银丝镶嵌工艺采用\"错金银\"古法，纹路永不脱落。核心卖点是\"声学优化\"：轸头内部挖空形成共鸣腔，可微调琴弦泛音。适用于顶级演奏家、古琴收藏家，竞品对比：钧天坊更重实用性，乐圣则强调艺术性与保值性。","key_specs":{"材质":"明代老檀木（约400年树龄），银丝纯度99.9%","适配琴弦":"所有古琴弦型，尤其适合丝弦（减少摩擦噪音）","重量":"单枚约11g，平衡老琴琴头过重问题","工艺":"手工雕刻+错金银，耗时72小时/枚","适用人群":"古琴收藏家、非遗传承人、高端礼品市场"}}
