 - fades the first real clip in and the final clip out with the `--video-fade` duration (default `DEFAULT_VIDEO_FADE`, currently 1 s); the black intro/logo pad respects this fade-in only when `INTRO_VIDEO_FADE_ENABLED` is `True`
 - displays optional per-file captions at bottom center with slightly off-white text and a soft shadow; use `|` to split caption lines
 - adds persistent bottom-left title/date/place and bottom-right `Bubulescu.Org` stamps

 - writes an MP4 file named like `YYYYMMDD_title.mp4` in the current directory by default; use `--out-dir DIR` to choose another output directory
 - takes `YYYYMMDD` from the first picture/video metadata, falling back to file modification date
