> [!NOTE]
> **Low Risk**
> Low risk: this is a data-only update to the NVIDIA GPU SKU table,
expanding supported memory variants without touching runtime logic.
> 
> **Overview**
> Updates the NVIDIA GPU SKU metadata so `RTX 3080 Mobile` now lists
both `16` and `8` GB VRAM options (previously only `8`), allowing
hardware detection/selection to recognize the 16GB model.
