A PSR-11 compatible dependency injection container.

Entry lifetimes
---------------

[](#entry-lifetimes)

Container entries use explicit lifetimes:

- `shared()` caches one instance per container (default for added entries)
- `scoped()` caches one instance per requesting container scope
- `transient()` never caches
- `value()` returns the configured definition as-is (for literals or raw closures)

```
$container->add('config', ['debug' => true])->value();
$container->add(Service::class)->shared();
$container->add(RequestContext::class)->scoped();
$container->add(Builder::class)->transient();
```

Scope mode
----------

[](#scope-mode)

Use `scope()` to create an isolated container for one unit of work:

```
$root = new Container();
$root->add('app-name', 'celema')->value();
$root->add('global-service', GlobalService::class)->shared();
$root->add('request-service', RequestService::class)->scoped();

$scope = $root->scope();
$scope->add(Request::class, $request)->value();

// ... resolve request-local services
$scope->reset();
```

After the first `scope()` call, the root container is sealed and no longer accepts structural mutations. Scope tags can inherit pre-defined root tags while keeping their own local caches.

Services that should be cleaned between scopes can implement `Celema\Container\Resettable` and will be reset during `$scope->reset()`.
