/**
 * Shared Tailwind CSS preset for all ManaCore apps
 *
 * This preset uses HSL-based CSS variables for theming.
 * Colors are defined as HSL values (e.g., "47 95% 58%") and
 * wrapped with hsl() in the Tailwind config for flexibility.
 *
 * Usage in tailwind.config.js:
 * ```
 * import preset from '@manacore/shared-tailwind/preset';
 *
 * export default {
 *   presets: [preset],
 *   content: ['./src/**\/*.{html,js,svelte,ts}'],
 *   // app-specific overrides...
 * }
 * ```
