/**
 * 数字口径机械防线（2026-09-19 critique P0 → 结构强制收尾）：
 * 1) 「目标口径，非既成结果」必须来自 METRICS_BASIS_NOTE 单一真源，不得散写字面量；
 * 2) 每个呈现结果型数字的渲染源（含详情页共享数字组件）必须接入 MetricsBasisNote；
 * 3) 走共享数字样式渲染的指标必须声明 basis（target|team-history|verified），
 *    且口径解析对缺失/非法值保守回落到最弱的 target；
 * 4) 禁止再引入「数字源自真实客户案例 / 经过实战验证」式虚构佐证（本站零公开客户案例）。
 * 扫描范围：src/app + src/components 的 .ts/.tsx（排除测试文件与 _archive 归档）。
