/* ═══ COLOR FLOW MAP (from design-spec.theme_context_map) ═══
 *
 * NAV: always-dark (#0F2840 solid) — logo always logo-light.svg — links always white
 *      Nav does NOT adapt per page. Always same dark solid nav.
 *
 * index.html (dark-top):
 *   body bg     → #0F2840 (dark, so transparent nav @ scroll=0 shows dark)
 *   hero        → DARK  (#0F2840)  | text: #F0F4F8 white
 *   trust-strip → DARK-ALT (#152E50) | text: #F0F4F8 white
 *   problem     → LIGHT (#F0F5FA)  | text: #0F2840 dark
 *   how-preview → WHITE (#FFFFFF)  | text: #0F2840 dark
 *   metrics     → DARK  (#0F2840)  | text: #F0F4F8 white
 *   features    → LIGHT (#F0F5FA)  | text: #0F2840 dark
 *   testimonials→ WHITE (#FFFFFF)  | text: #0F2840 dark
 *   eligibility-preview → DARK-ALT (#152E50) | text: white
 *   cta         → DARK  (#0F2840)  | text: white
 *   footer      → DARK  (#0F2840)  | text: #F0F4F8 white
 *
 * platform.html (dark-top): dark → light → white → light-alt → white → dark → light
 * how-it-works.html (light-top): light → white → light-alt → white → light → dark
 * eligibility.html (light-top): light → white → light-alt → white → light → dark

 * team.html (light-top): light → white → light → dark
 * contact.html (light-top): light → white (with nested dark map panel) → light
 * customers.html (dark-top): dark → light → white → dark
 * security.html (light-top): light → white → light-alt → dark
 * integrations.html (light-top): light → white → dark → light
 * solutions/*.html (dark-top): dark → light → white → dark
 * resources/index.html (light-top): light → white → light-alt → dark
 * blog/index.html (light-top): light → white → light-alt
 * blog/article.html (light-top): light → white → light-alt
 * status.html (light-top): light → white
 * login/*.html (dark-top): dark (split panel)
 * legal/*.html (light-top): light → white
 *
 * KEY RULES:
 * - dark-top pages: body bg = #0F2840 (transparent nav scroll=0 shows dark)
 * - light-top pages: body bg = default white/light (nav is solid dark ALWAYS)
 * - Adjacent dark sections need subtle border separator
 * - light-top + dark section at bottom (CTA) = dramatic contrast transition
