Applied on LXC 106 (backed up, `nginx -t`, reloaded) and recorded here: - Security headers (incl. CSP) moved to snippets/cinny-security-headers.conf and included at server level plus in the /sw.js, static-asset and json/html locations. nginx drops inherited add_header in any block that sets its own, so static assets were served without nosniff and /sw.js without a CSP (a service worker takes its CSP from its own script). Now every path carries all seven headers. Verified: the SW installs and controls the page under the CSP with no violations. - #214: CSP no longer allows fonts.googleapis.com / fonts.gstatic.com (VT323 is self-hosted since cinny 6f250353). - #155: the /share-target → /share 303 is now live (it was only in the repo; the 106 matrix-deploy hook has been dead since May, so repo edits never reached it). absolute_redirect off makes it relative. - README: the snippet, and that 106 needs these applied by hand.

# Security headers for chat.lotusguild.org (matrix repo: cinny/nginx-security-headers.conf).

# Included at server level AND in every location that sets its own add_header:
|
|
# nginx drops inherited add_header directives in any block that defines one,
|
|
# so without the include, static assets lost nosniff and /sw.js lost its CSP
|
|
# (a service worker's CSP comes from its own script response). cinny #210.
