- Parse NHC forecast advisory text (FORECAST VALID / OUTLOOK VALID lines) to extract real forecast positions at 9–117h intervals with wind speeds - Render forecast track as dashed line + clickable dots (wind on click) - Auto-fit map bounds to show the full 5-day track after loading - Fix buildStyle to use OpenFreeMap vector tile URLs without API key Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
