The set
Coaster 1 — CSP (Content Security Policy) · lock it down. default-src, script-src, nonce, report-uri.
Coaster 2 — HSTS · HTTPS only. max-age, includeSubDomains, preload. "you cannot go back — choose carefully."
Coaster 3 — CORS · who can call? Origin, Methods, Headers, Credentials, OPTIONS preflight.
Coaster 4 — Frames · no iframes. DENY, SAMEORIGIN, CSP frame-ancestors. Prevent clickjacking.
