-// LabelNamer is a helper struct to build label names.
-// It translates OpenTelemetry Protocol (OTLP) attribute names to Prometheus-compliant label names.
-//
-// Example usage:
-//
-//	namer := LabelNamer{UTF8Allowed: false}
-//	result := namer.Build("http.method") // "http_method"
-type LabelNamer struct {
-	UTF8Allowed bool
-}
-
-// Build normalizes the specified label to follow Prometheus label names standard.
-//
-// Translation rules:
-//   - Replaces invalid characters with underscores
-//   - Prefixes labels with invalid start characters (numbers or `_`) with "key"
-//   - Preserves double underscore labels (reserved names)
-//   - If UTF8Allowed is true, returns label as-is
-//
-// Examples:
-//
-//	namer := LabelNamer{UTF8Allowed: false}
-//	namer.Build("http.method")     // "http_method"
-//	namer.Build("123invalid")      // "key_123invalid"
-//	namer.Build("__reserved__")    // "__reserved__" (preserved)
