/**
 * Apex Peptides V3 — Swiss Multinational Biotech Executive Stylesheet
 * Design Benchmark: Bachem / Lonza / WuXi AppTec / MedChemExpress Corporate Aesthetic
 *
 * Key Architectural & Comfort Principles:
 * 1. Low-fatigue Swiss Pharma Palette: Alabaster White (#FFFFFF), Cool Polar Slate (#F6F8FB),
 *    Executive Midnight Navy (#0B1D33), Swiss Royal Blue (#16437E), Champagne Gold (#B5945B).
 * 2. Restrained CTA Hierarchy: Eliminates loud green button clutter across catalog cards;
 *    reserves Executive Emerald (#128040) strictly for primary consultation entry points.
 * 3. Generous 1320px executive grid, 1.72 body line-height, zero text/caption overlap,
 *    and non-intrusive right-edge collapsible concierge rail on desktop.
