/* ==========================================================================
   FarmTrace - Foundation CSS (design system layer)
   Loaded AFTER the template style.css so these rules win.
   --------------------------------------------------------------------------
   Purpose:
   - Neutralize template gradients and translucent surfaces with a solid,
     consistent color system (no gradients).
   - Standardize components: panels, metric cards, tables, forms, badges,
     alerts, empty states, pagination.
   - Add FarmTrace-specific utilities.
