   ✓ Modal overlay with backdrop blur
   ✓ Animated spinner (4 styles available)
   ✓ Loading text with animated dots
   ✓ Smooth slide-in animation
   ✓ Responsive design for all screen sizes

2. CSS STYLING (~250+ lines)

═══════════════════════════════════════════════════════════

🎯 HOW IT WORKS:
================

SCENARIO 1: Navigation
User clicks link → Preloader shows → Page loads → Preloader auto-hides

SCENARIO 2: Form Submit
User submits form → Preloader shows → Response returns → Preloader auto-hides

SCENARIO 3: AJAX Request
AJAX start → Preloader shows → AJAX complete → Preloader auto-hides

SCENARIO 4: Manual Control
Call Preloader.show() → User does something → Call Preloader.hide()

═══════════════════════════════════════════════════════════

🎨 SPINNER STYLES AVAILABLE:
=============================

1. CIRCULAR (Default) - Modern rotating circle
   Speed: 1.2s per rotation
   Best for: General purpose loading

2. DOTS - Three bouncing dots
   Speed: 1.4s per cycle
   Best for: Casual/friendly feel

3. PULSE - Pulsing circle with scale
   Speed: 2s per pulse
   Best for: Slow operations

4. BARS - 12 rotating bars
   Speed: 1.2s per rotation
   Best for: Professional look

⚙️ CONFIGURATION:
=================

Default Settings:
  minDuration: 300ms     (Minimum show time for UX)
  autoHideDelay: 10s     (Failsafe timeout)
  spinnerType: circular  (Can be changed in HTML)
  backdropBlur: 2px      (Subtle blur effect)
  animations: GPU        (transform-based, performant)

🚀 QUICK START:
===============

1. DEFAULT BEHAVIOR

   ✓ Works with all links and forms

2. DISABLE FOR SPECIFIC ELEMENTS
   <a href="/link" data-no-preloader>Link</a>
   <form data-no-preloader>...</form>

3. MANUAL CONTROL
   Preloader.show();  // Show preloader
   Preloader.hide();  // Hide preloader

4. CHANGE SPINNER STYLE
   Edit HTML in: resources/views/layouts/mobile/app.blade.php
   Change .spinner-circular to other spinner class
