/**
 * ============================================================================
 * FILE: main-styles.css
 * SECTION: All Styling (CSS)
 * ============================================================================
 * 
 * WHAT THIS FILE DOES:
 * Contains ALL the CSS styling for both pages (index.html and forecast.html).
 * This controls how everything looks - colors, spacing, fonts, layout.
 * 
 * DESIGN SYSTEM:
 * Stripe-inspired clean SaaS design
 * - Professional, trustworthy, data-forward
 * - High contrast, generous whitespace, subtle gradients
 * 
 * FILE ORGANIZATION:
 * 
 * 1. Design Tokens (CSS Variables)
 *    - Colors (--text, --surface, --border, etc.)
 *    - Spacing (--space-1, --space-2, etc.)
 *    - Typography (--font-family, --text-*, etc.)
 *    - Located in :root section
 * 
 * 2. Base Styles
 *    - CSS reset
 *    - Typography (headings, body text)
 *    - Body styles
 * 
 * 3. Layout Components
 *    - Topbar (navigation bar)
 *    - Shell (main container)
 *    - Hero (page header)
 *    - Grid layouts
 * 
 * 4. UI Components
 *    - Buttons (segmented controls, location/elevation buttons)
 *    - Cards (glance cards, forecast tiles, current card)
 *    - Panels (sections with headers)
 *    - Loading/error states
 * 
 * 5. Page-Specific Styles
 *    - Forecast page specific styles
 *    - Conditions page specific styles
 * 
 * 6. Responsive Breakpoints
 *    - Mobile, tablet, desktop layouts
 * 
 * WHEN TO EDIT THIS FILE:
 * ✓ Changing colors → Edit CSS variables in :root section
 * ✓ Changing spacing → Edit --space-* variables
 * ✓ Changing fonts → Edit --font-* and --text-* variables
 * ✓ Changing component styles → Find the component class and modify
 * ✓ Adding new styles → Add new CSS rules
 * ✓ Changing layout → Modify grid/flexbox properties
 * 
 * QUICK REFERENCE:
 *    Colors: Look for --text, --surface, --border variables
 *    Spacing: Look for --space-1 through --space-6
 *    Components: Look for class names like .panel, .card, .button
