/* dgcheck static fallback styling.
 *
 * A separate file rather than a <style> block because this origin's CSP
 * has no 'unsafe-inline' (ops/nginx/sites-available/dgcheck.aikeylabs.com).
 * If these pages used inline styles they would render unstyled, and the
 * first person to see that would be tempted to "fix" it by adding
 * 'unsafe-inline' to the CSP -- which is the whole thing we are protecting.
 * Self-hosted, no @import, no web font.
