// SMC Structure Context Overlay — visualizes v5.3 structure state
//
// Reads Structure State fields from the generated micro-profiles library:
//   • STRUCTURE_STATE (BULLISH / BEARISH / NEUTRAL)
//   • CHoCH / BOS event markers
//   • Active support / resistance levels
//   • Structure freshness indicator
//
// Keep on a separate pane — independent of trade signals.
