// Shared OptiSigns device matching and enrichment helpers for AV.
// This centralizes the logic previously duplicated in deviceService, avDeviceBuilder, and avEnricher.
//
// - findBestOptiSignsMatch: unified finder (prefers normalized exact match for consistency,
//   with loose contains fallback for compatibility).
// - createOptiSignsDisplay: produces the slim {content, lastHeartBeat, isOld} shape used by chat (/avstatus) and HTML.
// - createRichOptiSigns: produces the rich shape used by /build and modals (spreads raw + resolved names).
//
// Uses normalizePlayerName from normalizers and the resolution helpers from the OptiSigns client.
// Extracted as part of Option A incremental consolidation (after RED).
