pub const VIDEO_PAD_TOKEN_ID: u32 = _; // 151_656u32Expand description
2026-09-25: Fallback <|video_pad|> id, used when the checkpoint’s config declares
none (or 0). The Qwen3-VL, Qwen3.6 and Qwen3.8 checkpoints all put the
video token directly after the image token. A declared id always wins, as
for the image token.
