Improved: gradient banding
The top screen was RGB565 — blue had only 5 bits (32 levels) — so smooth gradients could only ever land in ~32 hard steps. That is the banding / "lines in the colour" visible against the official 3DS player.
The top screen is now 24-bit (8 bits per channel — 256 blue levels), in every path: the Y2R hardware converter, the software converter, and the subtitle renderer.
Colours are unchanged from the original release — this is purely a bit-depth fix. No decoder, playback or UI changes.
