Paper-space'de bir viewport'a çift tıklanıp aktif hale gelince, model space'deki gibi sol üst köşede render-mode dropdown'ı ve sağ üst köşede ViewCube gösteriliyor. - render_mode_picker helper'a çıkarıldı; model space ve aktif paper viewport ortak kullanıyor (kod tekrarı yok) - SetRenderMode artık viewport-aware: aktif viewport varsa o viewport entity'sinin render_mode'unu, yoksa model-layout tab stilini günceller (Scene::active_viewport_render_mode getter/setter) - build_viewport_primitive'e show_viewcube parametresi; aktif viewport primitive'i ViewCube gizmo'sunu çiziyor - PaperViewportPane shader::Program artık Message'a özelleşti ve sol tık ViewCube hit-test'ini bounds-relative yapıp ViewCubeSnap üretiyor Bilinen sorun: picker/viewcube doğru konumda görünüyor ancak tıklamalar üstteki viewport_mouse mouse_area katmanına gidiyor; katman sırası bir sonraki adımda düzeltilecek.
