/*
 * Microsoft 365-Inspired Cocovox Landing Page Theme
 * Combines MS365's clean, professional design patterns with Cocovox brand colors
 *
 * COLOR ARCHITECTURE:
 * - Text/surface/border colors use canonical CSS variables from design-tokens.css
 *   (--text-primary, --surface-card, --border-color-default, etc.)
 * - Dark mode is automatic via the theme system — no per-rule overrides needed
 * - Brand accent colors (#2D5B3E, #42c99f, #2bb5a8, etc.) stay hardcoded — they're mode-independent
 * - Landing-specific layout colors (header glass, hero gradient, etc.) use --landing-* variables
