Proactive security & health pass. No live/exploitable vulnerabilities were
found; these changes remove information-disclosure surfaces and add
standard hardening.
- Remove publicly-downloadable 1.1 MB full source dump (code_export.txt)
and stray empty l.php; add code_export.txt to .gitignore.
- Exclude dev files/folders (*.sh, *.py, docs/, templates/, tools/,
README.md) from the rsync deploy so they never reach the live server.
- .htaccess: add X-Frame-Options, Referrer-Policy, Permissions-Policy,
and a report-only Content-Security-Policy; add defense-in-depth deny
block for dev/VCS files (robots.txt & sitemap.xml left served).
- .htaccess: fix root redirect to canonical msosorg.com + /en/.
- Swap 4 project-page YouTube embeds to youtube-nocookie.com so no
Google cookies are set before consent (GDPR).
- Add rel="noopener" to 30 team social links on the About Us pages.
- Harden esc() in my-route.js to also escape single quotes.
