TV Composite Video (one scan line)
sync tip → back porch → active luminance
A single line of analog TV: a horizontal-sync tip drops below black to trigger retrace, a back-porch black level, then the picture's brightness — the waveform a CRT paints left-to-right.
Computed & rendered in pure C# on the frozen OnlyCSharp 1.8 library — animation baked to GIF with the library's own
Gif encoder (no GPU, no ffmpeg, no external packages).
