/**
 * Little Bites Menu System - Styles
 *
 * PURPOSE:
 * Complete styling for the Little Bites online menu ordering system.
 * Implements brand colors, responsive layout, and interactive animations.
 *
 * DESIGN SYSTEM:
 * - Primary color: #006dab (blue)
 * - Light accent: #E7F3FB
 * - Border radius: 18px (cards), 28px (pills)
 * - Font family: Poppins, Nunito (Canva Sans equivalents)
 *
 * KEY COMPONENTS:
 * 1. Layout
 *    - Max-width 650px container for readability
 *    - Sticky footer with submit button (mobile-optimized)
 *    - Card-based design with soft shadows
 *
 * 2. Menu Cards
 *    - Meal title, price, description dropdown
 *    - Quantity controls (+/- buttons)
 *    - Per-instance option selectors (pills)
 *
 * 3. Interactive Elements
 *    - Quantity buttons: Hover inverts colors, active scales down
 *    - Pills: Hover lifts with border, selected gets blue background
 *    - Submit button: Hover lifts, active presses, submitting pulses
 *
 * 4. Animations
 *    - All transitions: 0.15-0.2s ease timing
 *    - Transform effects: translateY, scale for press feedback
 *    - Pulse animation for submit button during processing
 *
 * 5. Validation & Error States
 *    - Red borders and background for invalid fields
 *    - Animated error messages with slideDown effect
 *    - Focus states clear errors automatically
 *
 * MOBILE OPTIMIZATIONS:
 * - Sticky footer uses left/right positioning for full width
 * - Box-sizing ensures elements fit within viewport
 * - Subtotal left-justified with "Tax not included" note
 * - Submit button centered with max-width constraints
 *
 * RECENT UPDATES (v2.1):
 * - Fixed sticky footer overflow on mobile devices
 * - Redesigned subtotal layout (left-justified with tax note)
 * - Added proper box-sizing to prevent horizontal scrolling
 * - Enhanced customer info validation styling
 *
