## 🎨 Theming & Styling

BloomAccordion automatically respects the active `BloomTheme` (including `BloomTheme.novaLight`, `BloomTheme.novaDark`, etc.) and responds seamlessly to dark mode changes, custom border radii, and brand color tokens.

### Theme Overrides Example
```dart
Theme(
  data: Theme.of(context).copyWith(
    extensions: [
      context.bloomTheme.copyWith(
        colors: context.bloomColors.copyWith(
          primary: const Color(0xFF8B5CF6), // Custom Purple Accent
        ),
      ),
    ],
  ),
  child: BloomAccordion(...,
)
```
