/**
 * SiteRecord Marketing Surface Stylesheet
 * 
 * DESIGN PRINCIPLES:
 * - Authoritative, not flashy
 * - Calm, not sterile
 * - Modern, not trendy
 * - Confident, not salesy
 * 
 * VISUAL LANGUAGE:
 * - Monochrome palette with subtle warm accents
 * - Strong typographic contrast and hierarchy
 * - Ledger-like structures, ruled lines, document metaphors
 * - Generous whitespace signaling seriousness
 * - No gradients, no feature-card grids, no SaaS sameness
