+/**
+ * Tutorial: split global services from context-specific services.
+ *
+ * Use this pattern when part of the app should be constructed once at the app edge,
+ * while another part should be cached per request/project/workspace key.
+ *
+ * In this example:
+ * - Npm.Service is the global service. It is not keyed by request context and should
+ *   be provided once by the application runtime.
+ * - ConfigService is context-specific. It is built from a RequestContext key and is
+ *   cached by LayerMap for that key.
+ * - ConfigServiceMap.layer owns the cache. Provide it once globally, then each
+ *   request can provide ConfigServiceMap.get(context) to select the right instance.
+ *
+ * Lifetime model:
+ * - ConfigServiceMap.layer has the app/global lifetime and depends on Npm.Service.
+ * - ConfigServiceMap.get(context) has the request/context lifetime and provides
+ *   ConfigService for exactly that context key.
+ * - The cached ConfigService entry stays alive while something is using it. Once idle,
+ *   it remains cached for idleTimeToLive, then its scope is finalized.
+ * - invalidate(context) removes the cache entry for future lookups. Active users keep
+ *   running on the old instance; the next lookup can create a fresh instance.
+ *
+ * Key model:
+ * - Keys can be strings, structs, classes, arrays, etc.
+ * - Prefer primitive or immutable keys. Effect uses Hash / Equal semantics for cache
+ *   lookup, so mutating an object after it has been used as a key is a bug.
