/*
	Security-first landing page helper CSS

	NOTE: This file contains CSS plus a recommended <head> snippet (below) as a commented
	HTML block. Paste the HTML into your document <head> and serve the CSP and other
	headers from the server (preferred) or via meta tags when appropriate.

	The recommendations follow OWASP best-practices: strict Content-Security-Policy,
	secure HTTP headers (HSTS, Referrer-Policy, X-Frame-Options), minimal inline
	scripts/styles, and strict resource loading rules. Always validate and escape
	user input on the server and use frameworks' safe templating to avoid XSS.

	Example <head> snippet (copy into your HTML head):

	<!-- Minimally permissive Content Security Policy: prefer sending this as an
			 HTTP header: Content-Security-Policy -->
	<!--
	<meta http-equiv="Content-Security-Policy"
				content="default-src 'self'; base-uri 'self'; form-action 'self';
								 frame-ancestors 'none'; object-src 'none'; script-src 'self' 'nonce-REPLACE_WITH_SERVER_NONCE';
								 style-src 'self' 'nonce-REPLACE_WITH_SERVER_NONCE';
								 img-src 'self' data:; connect-src 'self'; font-src 'self';">

	<meta http-equiv="X-Content-Type-Options" content="nosniff">
	<meta http-equiv="X-Frame-Options" content="DENY">
	<meta name="referrer" content="no-referrer">
	<meta http-equiv="Permissions-Policy" content="geolocation=(), microphone=(), camera=()">
	<!-- Serve Strict-Transport-Security as an HTTP header in production -->
	<!-- Strict-Transport-Security: max-age=63072000; includeSubDomains; preload -->
	-->

/*
	Styling guidelines:
	- Avoid using inline styles or inline event handlers (onclick=) which bypass CSP.
	- Use server-generated nonces for scripts/styles you must allow inline.
	- Keep forms protected by CSRF tokens; never rely on client-only protection.
