/**
 * Onyx notification theme for PHPFlasher.
 *
 * The Onyx theme provides a modern, refined visual style with:
 * - Clean, floating cards with elegant shadows
 * - Small accent dots in the corners indicating notification type
 * - Generous rounded corners for a contemporary look
 * - Smooth entrance animation with blur transition
 * - No icons, maintaining a minimal, focused design
 * - Subtle progress indicator at the bottom
 *
 * This theme creates a sophisticated appearance that integrates
 * well with modern interfaces while providing clear status information.
 *
 * @example
 * ```typescript
 * import flasher from '@flasher/flasher';
 * import { onyxTheme } from '@flasher/flasher/themes';
 *
 * // Register the theme (if not already registered)
 * flasher.addTheme('onyx', onyxTheme);
 *
 * // Use the theme
 * flasher.use('theme.onyx').success('Your changes have been saved');
 * ```
