 Once browser-direct succeeds, the system caches this state and skips fallback tiers on subsequent requests. Country-specific markets are fetched by mapping countries to Polymarket tags with name-variant matching (e.g., "Russia" matches titles containing "Russian", "Moscow", "Kremlin", "Putin").
 
 Markets are filtered to exclude sports and entertainment (100+ exclusion keywords), require meaningful price divergence from 50% or volume above $50K, and are ranked by trading volume. Each variant gets different tag sets — geopolitical focus queries politics/world/ukraine/middle-east tags, while tech focus queries ai/crypto/business tags.
