   DESIGN TOKEN MIGRATION - IN PROGRESS
   
   STATUS: Partial migration complete
   - Utility classes exist (.u-hidden)
   - Many hard-coded hex colors remain (200+ instances)
   - TODO: Replace all hex/rgba with tokens from css/1-base.css
   - TODO: Add additional utility classes as needed
   
   Use tokens from css/1-base.css instead of hard-coded values.
   Allowed exceptions: literal 1px borders, calc() with tokens

/* ========================================================================== */
/* CORE COMPONENT USAGE GUIDE
 * 
 * These core classes provide the foundation for all UI components:
 * 
 * .u-hidden
 *   - Utility class for hiding elements with !important
 * 
 * .btn (base) + variant classes
 *   - Use .btn as the foundation for all buttons
 *   - Add .btn-primary, .btn-secondary, or .btn-danger for styling
 *   - All sizing and padding comes from .btn; variants only change colors/shadows
 *   - Example: <button class="btn btn-primary">Click me</button>
 * 
 * .card (generic container)
 *   - Use for any card-like container (sections, boxes, etc.)
 *   - Add .elevated modifier for increased shadow
 *   - Includes base padding, border, and hover effects
 * 
 * .badge (small labels) + variant classes
 *   - Use .badge for small inline labels and status indicators
 *   - Add .badge-primary, .badge-danger, .badge-success, or .badge-warning
 *   - Use for tags, status labels, plan indicators, etc.
 * 
 * REFACTORING PATTERN:
 *   1. Extract shared visual properties to the base class
 *   2. Keep layout-specific rules in component-specific classes
 *   3. Example: items can inherit card styling while keeping layout rules
 *   4. Use modifier classes (.btn-primary) instead of creating new button types
 *
