Python-Based Automated Video Assembly Logic

Act as a Senior Python Video Engineer. Draft a highly complex, mathematically rigorous Python logic framework (leveraging libraries such as `MoviePy` or a direct FFmpeg wrapper) engineered to act as a completely autonomous, 'zero-human-input' video editor. The script architecture must be programmed to automatically traverse a rigid [ASSET_FOLDER_STRUCTURE], blindly ingesting raw `.wav` voiceover files from one directory, and sequential `.mp4`/`.png` visual assets from another. The core logic must dynamically calculate the exact lengths of the audio files and perfectly sync the visual cuts based on an imported JSON/SRT timestamp array. The code must programmatically inject a uniform [TRANSITION_STYLE] (e.g., a 0.5s crossfade) between every single clip, and automatically render and composite complex [OVERLAY_REQUIREMENTS] (e.g., dynamic lower thirds, a scrolling progress bar, and hardcoded subtitles) directly onto the final output buffer before executing the final `.mp4` render.
