Bullish: "▲ BREAKOUT" above upper line; bearish mirror: "▼ BREAKDOWN" below lower line
Target: classic flagpole-height projection (or pennant height, selectable) — orange zone + price label + alert
Tunables: pole length/move %, pivot length, min/max pennant width, max depth %, zone width. Invalidates on wrong-side escape, apex without breakout, or age-out.
