Public index and canonical security.txt
2.4.8 separates the machine sitemap from its human-readable view, publishes a visual FR/EN index and normalises the security.txt entry point without changing the engine.
- New dark, readable /sitemap page automatically powered by the same catalog as sitemap.xml
- The XML sitemap remains machine-focused and keeps lastmod, hreflang and automatic generation
- Root security.txt redirects to /.well-known/security.txt, which exposes email, Contact page, expiration, languages, canonical and policy
- Engine, GPTO, 2026.09.4 patterns and MariaDB schema 2.3.1 unchanged; no SQL migration
