prompt: Extremely fast-paced first-person POV cinematic shot sprinting on the back of a massive brown grizzly bear at full gallop, camera positioned directly behind the bear's head showing both small rounded ears pinned back, thick brown fur rippling with each powerful stride, muscular shoulders pumping intensely, rider's hands visible in tan leather gloves gripping worn leather reins attached to a simple harness. The bear charges forward at breakneck speed through an ancient old-growth temperate rainforest, paws thundering across a muddy trail covered in tangled exposed tree roots and scattered branches, mud and debris kicking up with each stride.
