/* =============================================================================
   Mail Admin — stylesheet
   An internal ops tool: legibility and density over flourish. One accent
   (deep teal, chosen for its infrastructure/network feel — deliberately not the
   default cream+terracotta look). The signature is typographic: every exact,
   copy-me-verbatim string (domains, DNS records, hashes, commands) is set in
   monospace, so "this is data you must reproduce faithfully" is visible at a
   glance. Everything else is quiet system sans.
