场景一：户外露营·黑夜救星 (The Camping Savior)
💡 核心逻辑： 在绝对黑暗的环境中展示亮度和模式切换，最后展示给手机充电的救急功能。Vertical POV video. First-person view of walking on a pitch-black forest trail at night. A hand raises a rugged, high-quality metal flashlight and clicks it on. Instantly, a massive, blinding beam cuts through the darkness (High Mode). The thumb clicks the button again, dimming the light to a soft glow (Low Mode), and clicks once more to activate a rapid emergency strobe (Strobe Mode). The person stops, holds up a smartphone showing a "Low Battery" red icon, plugs a USB cable into the flashlight, and the phone screen instantly lights up green with "Charging". Authentic outdoor night vibe.
