Pure first-person flying camera perspective, no visible drone, no aircraft, no propellers. The camera races through a collapsing crystal canyon, skimming over glowing rivers, weaving between floating shards, then diving into a huge mirror portal. Final reveal: the canyon reflects into infinite copies of itself, exploding into a kaleidoscope universe of light. Seamless one-take, aggressive banking, realistic inertia, ultra-fast POV, high-end VFX, cinematic motion blur, volumetric glow, hyper-realistic.
