/*
 * VISUAL DNA ANALYSIS — Source: BizConsult Consulting Template
 *
 * 1. LAYOUT DNA: Full-width alternating sections with contained content (~1140px),
 *    split two-column hero (text + image), generous vertical rhythm (6rem padding).
 *    Sections alternate between white and colored backgrounds.
 *
 * 2. VISUAL RHYTHM: Alternating white / primary-colored bands. Small rounded-pill
 *    labels above section headings create a repeating motif. Soft box-shadows on
 *    cards. Large spacing between sections (6rem).
 *
 * 3. DISTINCTIVE FEATURES:
 *    - Rounded-pill section labels & buttons
 *    - Corner-radius icon containers (asymmetric: 5px 0 or 0 5px)
 *    - Soft 45px box-shadows that disappear on hover (replaced by border)
 *    - Dark navy (#0E2E50) footer with light text
 *    - Wavy/curved section dividers
 *
 * 4. COLOR STRATEGY: White base + vibrant teal (#00B98E) primary + dark navy (#0E2E50)
 *    for footer/accents. Light gray (#F3F6F8) subtle background. High contrast.
 *
 * 5. TYPOGRAPHY FEEL: Clean geometric sans-serif. Heebo (body) + Inter (headings).
 *    Medium weight body, bold/extra-bold headings. Modern corporate clarity.
 *
 * 6. COMPONENT STYLE: Rounded-pill buttons (border-radius: 50px), cards with
 *    shadow-to-border hover transitions, underline nav hover effects, circular
 *    icon badges with primary background.
