+// title_scene_3d.hpp - Variant 3D real de l'escena de títol
+// © 2026 JailDesigner
+//
+// Clon de `TitleScene` (2D) que substitueix `Graphics::Starfield` per
+// `Graphics::Starfield3D` i `Title::ShipAnimator` per `Title::ShipAnimator3D`,
+// afegint una `Graphics::Camera3D` que projecta l'escena en perspectiva real.
+// Tot el bloc d'overlay 2D (logo "ORNI ATTACK!", "PRESS START TO PLAY", peu
+// "JAILGAMES + copyright") es manté idèntic.
+//
+// Trigger: env var `ORNI_TITLE_3D=1` interceptada al `Director::buildScene`,
+// o transicions explícites a `SceneType::TITLE_3D`.
