chore: baseline snapshot before moderation-strictness feature

Repo .git was damaged (refs/ missing, index truncated, object store near-empty). Repaired via git init (rebuilt refs), stale index preserved as .git/index.corrupt-20260910.bak, then full worktree committed as a rollback baseline.

+# bench-cdn.sh — UIkit CDN 测速脚本（国内 / 海外双视角）
+#
+# 用途：对比"自建 R2 自托管 uikit"与"公共 CDN (cdnjs.snrat.com)"的加载速度，
+#       用于验证/复测 2026-09-05 的 CDN 迁移是否持续生效。
+#
+# 用法：
+#   bash dev/bench-cdn.sh cn      # 国内本机：每资源 5 次全量下载取中位
+#   bash dev/bench-cdn.sh global  # 海外：check-host.net 多区域节点 (p50/p90)
+#
+# 数据结论参考（2026-09-05 基线，国内中位）：
+#   css    R2 0.864s  -> snrat 0.200s   (4.3x)
+#   js     R2 0.796s  -> snrat 0.163s   (4.9x)
+#   icons  R2 0.824s  -> snrat 0.177s   (4.7x)
+#   海外（check-host p50）：css 打平；js R2 372ms vs snrat 647ms (R2 略快)
+# 结论：站点访客以国内为主 -> snrat 净收益大；海外属轻微下降可接受。
