/*
 * Dr.D Design System
 * Version: 2026-04-05
 * Source alignment: TidyCal Client Portal runtime theme
 *
 * Usage:
 * 1. Import this file after any reset or normalize.
 * 2. Wrap the page or application root with `.drd-theme`.
 * 3. Use the `.drd-*` classes to avoid collisions with host styles.
 * 4. Override only the CSS custom properties if you need to rebrand.
