/*

CRITICAL RULES:

1. HEADINGS (H1-H6):
   - Always use: font-heading text-obsidian
   - Never use pure black (#000000)
   - Example: <h1 class="font-heading text-h1 text-obsidian">

2. BODY TEXT:
   - Always use: font-body text-obsidian-soft
   - Never use Afacad Flux Light (300) - readability first
   - Example: <p class="font-body text-body text-obsidian-soft">

3. PETRONA ACCENT (.accent):
   - ONLY in H1-H2 headlines
   - ONLY for 1-3 emotional/human words
   - NEVER in H3-H6, body text, or navigation
   - ALWAYS italic (never upright)
   - Example: <h1>Engineering <span class="accent">intelligent</span> growth</h1>

4. GRADIENTS:
   - ✓ DO: Sage monochromatic (sage-500 → sage-900)
   - ✗ NEVER: Sage + Coral (creates brown/mud in middle)
   - Use: bg-gradient-to-br from-sage-500 to-sage-900

5. BUTTONS:
   - Standard height: h-btn (48px)
   - Always: font-heading font-bold rounded-btn
   - Primary: bg-obsidian hover:bg-sage-500
   - Conversion: bg-coral-500 hover:bg-coral-700

6. SPACING:
   - Sections: py-section (80px)
   - Hero sections: py-hero-section (128px)
   - Cards: p-card (32px)

7. ACCESSIBILITY:
   - Body text is 20px (not 16px) for 40-60 age group
   - Never reduce below 16px for any readable text
   - Line-height 1.7 for optimal readability
