Scene transitions, parallax background, sci-fi UI kit
- SceneTransitioner: fade-to-black between scenes with a sceneReady
- SceneTransitioner: fade-to-black between scenes with a sceneReady signal so the fade-in ends as soon as the destination UI is built (no more ~1s safety timeout on normal transitions).
- ParallaxLayer: ambient sin-wave drift for background layers (far / mid / near) on the main menu.
- MenuButtonHover: hover/press color feedback for sci-fi buttons.
- SciFiMenuKit: shared helpers for panel, full-border, sci-fi button, text, background image + vignette so every scene reads consistent.
