 Modular monolith using Core PHP Framework (Laravel 12). Modules live in `app/Mod/{Name}/Boot.php` and register via events.
 
+**Bootstrap chain:** `bootstrap/app.php` loads four Core providers in order:
+1. `Core\LifecycleEventProvider` — fires lifecycle events that modules listen to
+2. `Core\Website\Boot` — website layer
+3. `Core\Front\Boot` — frontend/middleware layer
+4. `Core\Mod\Boot` — discovers and registers all modules from paths in `config/core.php`

+- `app/Core/` — framework-level overrides (EUPL-1.2 copyleft)
+- `app/Mod/` — feature modules (your licence)

+**Routing:** The top-level `routes/web.php` and `routes/api.php` are boilerplate stubs. All real routes are registered by modules via `Boot.php` event listeners.
