/**
 * ICP Page Styles — CLO-354: ICP Page Template Component
 * Agent: FRAME
 *
 * Layout and visual styles for the reusable ICP vertical page template.
 * All 5 ICP pages (construction, infosec, healthcare, professional services,
 * SMB ops) share these styles with vertical-specific class overrides.
 *
 * Sections:
 *   1. Hero (icp-hero)
 *   2. Pain Cards (icp-pain-cards)
 *   3. Reframe (icp-reframe)
 *   4. Proof / Case Study (icp-case-study)
 *   5. How It Works (icp-process)
 *   6. Agents vs Your Team (icp-comparison)
 *   7. FAQ (icp-faq)
 *   8. CTA (icp-cta)
 *
 * Design Constraints:
 *   - All colors via CSS custom properties (no raw hex)
 *   - Bronze accent max 10-15% of viewport
 *   - Cream background, never white
 *   - Mobile-first (375px base), breakpoints at 768px and 1024px
 *   - prefers-reduced-motion respected throughout
 *   - Reuses existing component styles: proof-bar, testimonial, hybrid-figure
 *
 * Dependencies:
 *   - tokens.css
 *   - typography.css
 *   - proof-bar.css (proof bar grid, comparison bars)
 *   - testimonial.css (testimonial card pattern)
 *   - hybrid-figure.css (illustration system)
