1. ``--attention-config '{"backend": "FLASH_ATTN"}'``

``flash_attn_version`` is forced to 4 if not already set (R-SWA

mask_mod requires FA4; FA3 cannot express it). Raises if FA4 is
|
|
not available on this device.

2. ``--attention-config '{"backend": "FLEX_ATTENTION"}'``

→ FlexAttention R-SWA via Triton block mask.

3. ``--attention-config '{"backend": "TRITON_ATTN"}'``

4. ``--attention-config '{"backend": "auto"}'`` (or omitted)

blocks are not reusable), and single-turn image-led OCR prompts rarely
