/* ═══════════════════════════════════════════════════════════════════════════════
   WILLOW DESIGN SYSTEM
   Unified theme tokens for Budget / Accounting / Treasury modules.

   LOADING ORDER:
     1. tailwind.css (base)
     2. willow-ui.css  ← THIS FILE (design tokens + light overrides)
     3. module-specific CSS (navbar.css, theme files, inline <style>)

   PHILOSOPHY:
     - Define CSS custom properties as the source of truth.
     - Only override elements that directly fight dark mode or theme.
     - Avoid bulk !important — use high specificity instead.
     - Respect existing inline styles; don't fight them blindly.
