_headers

# NOTE: This file uses Netlify / Cloudflare Pages syntax. GitHub Pages — which
# serves this site today — silently IGNORES the rules below. The values are
# kept here as a single source of truth for an eventual move to Cloudflare
# Pages or Netlify, and as a reference for the security headers the project
# intends to enforce in production. The subset of headers that browsers honour
# from in-document <meta http-equiv> tags is mirrored elsewhere in the site
# chrome where applicable; CSP via <meta> is intentionally not added here
# because it cannot express the same directive set as a real HTTP header.
