/* trustedaigov.io — SaaS platform site
   Reuses the established TrustedAIGov product-io brand system (same tokens, Inter + JetBrains Mono,
   dark theme, nav, buttons, cards, footer) and adds .io-specific components:

   Public product names only — internal engine names (Invariant/Active/Intelligence/AUDIT AI) never appear. */
