       - Hero centered, premium business-skyline imagery
       - About: clean evergreen, no boxed framing
       - Vision / Mission: larger pills, generous spacing
       - Core Values: SVG kite-diamonds (crisp, no overlap)
       - Built For Business Longevity: line-broken cleanly
       - Why Choose Us: SVG octagonal frames (corners join)
       - Expertise: YA-specific practice areas
       - en-only / zh-only pattern for HTML-rich headlines
