/* =============================================================================
   base.css — Venture Factory Shared Design System — Version: 3.0

   RULE: Never edit this file per venture. Zero hardcoded colours or fonts.
   All venture values live in tokens.css.

   Load order in index.html — non-negotiable:
     <link rel="stylesheet" href="tokens.css" />   ← first
     <link rel="stylesheet" href="base.css" />     ← second

   FONT NOTE: --font-primary and --font-secondary are declared ONLY in tokens.css.
   This file uses var(--font-primary) without declaring the variable, so tokens.css
   always provides the value and base.css never overwrites it.
