/* ==========================================================================
   CreatorVault — A Copper Bay Labs product
   Standalone stylesheet (no @import). Forked from the LeakCheck / DepCheck
   build for cohesion across the Copper Bay Labs suite. Design system: Copper
   Bay Labs (Fraunces + Hanken Grotesk; copper #bf6b3c primary action,
   bay/teal #13525a accent, paper bg). Fonts loaded via Google Fonts <link>.

   CreatorVault ships two free, client-side tools:
     1. A cryptographic license-key generator (Web Crypto API).
     2. A creator-fee comparison calculator.
   The shared chrome (.masthead, .hero, .btn, .feature, .detect-grid, .faq,
   .footer) matches LeakCheck/DepCheck verbatim; tool-specific components are
   namespaced below.
