/*
 * Ricardo Valverde Photography LLC - Typography
 * Bold, modern type system with fluid responsive scaling
 *
 * ===========================================================================
 * TYPOGRAPHY PHILOSOPHY
 * ===========================================================================
 *
 * "BOLD BUT READABLE"
 * WHY: Stand out in fine art photography market
 * - Heavy font weights (700-800): Confident, premium gallery aesthetic
 * - High contrast: Easy to scan
 * - Generous line-height: Comfortable reading
 *
 * SYSTEM FONTS DECISION:
 * WHY NOT custom web fonts (like Google Fonts):
 * ✅ Performance: 0ms load time (vs 100-500ms for web fonts)
 * ✅ Familiarity: User's native UI font
 * ✅ Accessibility: User's chosen font with customizations
 * ✅ Privacy: No Google tracking
 * ✅ Cost: $0 vs $199/year for premium fonts
 *
 * ❌ Trade-off: Less unique branding
 * ✅ Solution: Bold colors + layout make us distinctive
 *
 * ===========================================================================
 * FLUID TYPOGRAPHY - clamp() Function
 * ===========================================================================
 *
 * WHY CLAMP: Smooth scaling between breakpoints
 * Old way: Fixed sizes with media query jumps
 * - 320px: 24px
 * - 768px: 32px (sudden jump!)
 * - 1200px: 48px (another jump!)
 *
 * New way: Smooth scaling with clamp()
 * - clamp(min, preferred, max)
 * - min: Smallest size on mobile
 * - preferred: Fluid size based on viewport (vw units)
 * - max: Largest size on desktop
 *
 * EXAMPLE: h1 { font-size: clamp(2rem, 5vw, 3.5rem); }
 * - Mobile (320px): 2rem = 32px (minimum)
 * - Tablet (768px): 5vw = 38.4px (scales smoothly)
 * - Desktop (1400px): 3.5rem = 56px (maximum)
 *
 * BENEFITS:
 * ✅ Smooth scaling: No jarring size jumps
 * ✅ Less code: No media queries needed for font sizes
 * ✅ Viewport-aware: Automatically adapts
 * ✅ User control: Respects browser font size settings
 *
 * BROWSER SUPPORT: 90%+ (IE11 not supported)
 * Fallback: Browsers without clamp() use middle value (5vw)
 *
 * ===========================================================================
 * TYPE SCALE - Modular Scale Ratio 1.25 (Major Third)
 * ===========================================================================
 *
 * WHY MODULAR SCALE: Visual hierarchy and harmony
 * - Each size is 1.25x the previous
 * - Creates consistent rhythm
 * - Music theory: Major third interval (pleasing ratio)
 *
 * SCALE:
 * h1: 56px (3.5rem) - Hero headlines
 * h2: 44px (2.75rem) - Section titles
 * h3: 32px (2rem) - Subsection titles
 * h4: 24px (1.5rem) - Card titles
 * h5: 20px (1.25rem) - Small headings
 * body: 16px (1rem) - Base text
 * small: 14px (0.875rem) - Meta text
 *
 * RESPONSIVE SCALING:
 * Ratio compresses on mobile (less dramatic hierarchy)
 * Expands on desktop (more dramatic contrast)
 *
 * ===========================================================================
 * LETTER SPACING (Tracking)
 * ===========================================================================
 *
 * WHY NEGATIVE LETTER SPACING on large headlines:
 * - Optical correction: Large text looks too loose
 * - Professional: Tighter = more polished
 * - Industry standard: Apple, Stripe use negative tracking
 *
 * h1: -0.02em (-2% of font size)
 * h2: -0.01em (-1% of font size)
 * h3+: 0em (normal spacing)
 *
 * ===========================================================================
 * LINE HEIGHT (Leading)
 * ===========================================================================
 *
 * HEADINGS: 1.2 (tight)
 * WHY: Multi-line headings should feel connected
 * Too loose (1.5): Feels disconnected, harder to read
 *
 * BODY TEXT: 1.6 (comfortable)
 * WHY: Balance readability and density
 * WCAG recommendation: 1.5 minimum
 * 1.6: Extra breathing room for long-form content
 *
 * ===========================================================================
 * UTILITY CLASSES
 * ===========================================================================
 *
 * .text-xs, .text-sm, .text-lg, .text-xl:
 * WHY: Quick size adjustments without custom CSS
 * Use case: Fine-tune specific elements
 *
 * .text-center, .text-left, .text-right:
 * WHY: Common alignments, saves repetition
 *
 * .text-muted, .text-primary, .text-accent:
 * WHY: Semantic color control
 * Better than inline styles: Consistent, themeable
