/*
Design philosophy for every stylesheet: 抖音揭秘 uses neon cinematic Chinese creator-studio aesthetics. The page must feel like a film set corridor and AI editing control room, with deep ink-blue surfaces, candy-apricot brand glow, electric cyan interaction cues, and warm film-gold credibility accents. Every visual decision should reinforce professional video media, not dilute it.
