 3. **CSS variables**: `--ag-*` properties mapped to design system tokens (`var(--card)`, `var(--foreground)`, etc.)
 4. **Interactive states**: Use `color-mix()` for hover/selection (NEVER hardcode hex/rgb)
+5. **Dark mode**: `.dark .ag-theme-quartz.ag-theme-claude` sets `color-scheme: dark` for native scrollbars/controls
+6. **Explicit fallbacks**: `.ag-root-wrapper` and `.ag-body-viewport` get direct `background-color` overrides in case CSS variable inheritance doesn't cascade through AG-Grid's internal DOM

+### Variable Categories
+
+The theme CSS defines variables across these groups:
+- **Core**: `--ag-background-color`, `--ag-foreground-color`, `--ag-data-background-color`, `--ag-border-color`, `--ag-secondary-border-color`
+- **Header**: `--ag-header-background-color`, `--ag-header-foreground-color`, `--ag-header-cell-hover-background-color`
+- **Rows**: `--ag-odd-row-background-color`, `--ag-row-hover-color`, `--ag-row-border-color`, `--ag-selected-row-background-color`, `--ag-range-selection-background-color`
+- **Controls**: `--ag-input-focus-border-color`, `--ag-input-border-color`, `--ag-checkbox-checked-color`, `--ag-toggle-button-on-background-color`
+- **Text**: `--ag-secondary-foreground-color`, `--ag-disabled-foreground-color`
+- **Panels/Menus**: `--ag-control-panel-background-color`, `--ag-menu-background-color`, `--ag-panel-background-color`, `--ag-modal-overlay-background-color`, `--ag-tooltip-background-color`
+
+**Critical**: `--ag-data-background-color` MUST be set explicitly — it controls the data viewport area and defaults to white if omitted, breaking dark mode.
