/* =============================================================================
 * LOADMATE — Design System (v2.1.0)
 *
 * Foundational tokens, typography, components, and utilities for the website
 * revamp. Loaded on every page via inc/enqueue.php.
 *
 * Structure:
 *   1. CSS custom properties (design tokens)
 *   2. Reset and base
 *   3. Typography
 *   4. Buttons
 *   5. Cards
 *   6. Sections, containers, layout
 *   7. Forms
 *   8. Utilities
 *   9. Animations (subtle, performance-budget-friendly)
 *
 * Mobile-first throughout. Breakpoints:
 *   - default: < 768px (mobile)
 *   - md: 768px (tablet)
 *   - lg: 1024px (desktop)
 *   - xl: 1280px (wide)
 *
 * Class naming: BEM-ish (.lm-block__element--modifier) to avoid collision
 * with Astra parent and any builder output.
 *
 * To roll back the design system entirely: remove the enqueue line in
 * inc/enqueue.php. The file can remain in /css/ harmlessly.
