 The first performance bottleneck was draw calls. Some assets were exported as many small GLTF primitives even when they used only a few materials.

 `generateur` was especially expensive because three visible instances could multiply thousands of primitives into thousands of draw calls. Instancing reduces repeated instance cost, but the source asset still needs a cleaner export.

 This prevents the overlay from jumping backward when nested loaders finish in a slightly different order.
 
+After the initial map boot is complete, late loading signals no longer reopen the full-screen loading overlay. Instead, `HomePage` shows the compact `AppLoadingIndicator` while the game remains visible. This is reserved for explicit runtime reload signals such as graphics preset changes, repair-state transitions, or late world loading events; chunk streaming intentionally does not drive this indicator.
