/* ========================================================================
   iOS Safari Touch Optimization Utility Classes
   ======================================================================== */

/*
 * BACKGROUND: iOS Safari Touch Event Issues
 * ----------------------------------------
 * iOS Safari has specific touch handling behaviors that can make buttons and
 * interactive elements unresponsive or behave inconsistently. This is particularly
 * problematic with HTMX-powered buttons where users may experience:
 * - Buttons not responding to touch/tap
 * - Delayed or missed touch events
 * - Inconsistent behavior between different button implementations
 *
 * SOLUTION: Three-Part iOS Touch Fix
 * ----------------------------------
 * 1. cursor: pointer - Ensures proper cursor behavior
 * 2. -webkit-tap-highlight-color: rgba(0,0,0,0) - Removes iOS blue tap highlight
 * 3. touch-action: manipulation - Optimizes touch handling for interactive elements
 *
 * IMPLEMENTATION HISTORY:
 * - Original fix implemented in PR #241 for iPhone modal button unresponsiveness
 * - Refactored to utility classes in Session 20 (September 6, 2025) for maintainability
 * - Extended across all appointment interface templates for consistency
 *
 * USAGE GUIDELINES:
 * - Use .htmx-button for HTMX-enabled interactive buttons (primary use case)
 * - Use .ios-touch for general interactive elements needing iOS optimization
 * - Use .btn-ios for enhanced button-specific iOS touch handling
 * - Always pair with ontouchstart="" attribute in templates for maximum compatibility
 */

/* General iOS touch optimization for any interactive element */

  cursor: pointer;
  -webkit-tap-highlight-color: rgba(0, 0, 0, 0);

}

/* Enhanced button-specific iOS touch optimization */
.btn-ios {
  cursor: pointer;
  -webkit-tap-highlight-color: rgba(0, 0, 0, 0);
  touch-action: manipulation;
}

/*
 * PRIMARY UTILITY: HTMX-enabled buttons
 * ------------------------------------
 * Use this class for all buttons that use HTMX for dynamic interactions.
 * This ensures consistent, reliable touch behavior on iOS devices.
 *
 * Example usage:
 * <button class="bg-green-600 hover:bg-green-700 text-white htmx-button"
 *         hx-post="/api/endpoint/"
 *         ontouchstart=""
 *         aria-label="Descriptive action">Action</button>
