From d4d46b085e2fed1b4b2a1902ba43021e55c2504b Mon Sep 17 00:00:00 2001

Subject: [PATCH] fix(deploy): content-hash cache-busting + block source/config
 leaks + real 404s

- build.sh stamps ?v=<md5> on JS/CSS refs; Cloudflare was serving 4h-stale bundles
- nginx: 404 for .mjs/.md/.yml/.sh/.conf/Dockerfile/dotfiles (build-pages.mjs, README, compose were public)
- nginx: unknown paths 404 instead of soft-404 SPA fallback (Search Console soft-404s)
- track live nginx.conf in repo
