/**
 * Semantic attributes for OpenTelemetry instrumentation.
 *
 * This module defines attribute keys following OpenTelemetry semantic conventions
 * with Optimizely-specific extensions. Attributes provide context for spans and logs,
 * making it easier to filter, search, and analyze telemetry data.
 *
 * Standard OTEL attributes follow the http.* namespace for HTTP operations.
 * Custom Optimizely attributes use the optimizely.* namespace.
