From-host ``window<{tag, list<ui32>}>`` with a 2-bit bulk count.
The 2-bit count caps each burst at 3 items, so the host splits the 7-element
list into three bursts (3 + 3 + 1). Because the header content (ui16 tag +
2-bit count = 18 bits) is narrower than the 32-bit data frame, this is the
sub-byte / misaligned-static-field frame layout the byte-granular codegen got
wrong. Hardware reassembles the bursts via `ListWindowToParallel`, checks the
tag and every item, and latches the result into the ``match`` MMIO region.
