/* Cyber Serenity Consulting — cyberserenityconsulting.com
   Palette and monospace identity carry over from the CSC logo: green on black.
   Body copy is set in a system sans for readability at small sizes; monospace
   is reserved for chrome (nav, eyebrows, labels, buttons) so it stays a
   signature rather than a legibility tax. No web fonts — nothing loads from a
   third party, which is what keeps the CSP free of external origins. */
