+/**
+ * 门户主题 favicon 兜底资产生成器（4 套皮肤各一份）
+ * - 输出 templates/themes/<theme>/assets/favicon.svg + favicon.png(128×128)
+ * - head.html 在 site.config['favicon'] 未配置时输出 url.asset('favicon.png')（见 fragments/head.html）
+ * 图形语言对齐种子 logo-8 系（圆点+书脊），主色取各主题 theme.json 的 primary 参数默认值；
+ * 小尺寸下高对比扁平化：无边框、无环形留白。
+ * 用法：node theme-favicons.cjs （在 front/ 下执行，依赖 ./node_modules/ws 与系统 Edge）
