2026-03: Interactive globe added to the docs home

What changed

• added an interactive globe to the landing page
• visitors can rotate the globe and click mock hotspots
• the side panel switches between regional brief, relation links, and mock hub output

Why it matters

The home page now shows the product language directly instead of asking visitors to infer it from static text first.

User impact

• faster first-click understanding of geopolitical and market routing
• clearer map between regional events, relation arcs, and downstream idea paths
• lower text density on the first screen
