What

Color targets with the SW_64KB_S swizzle (CB_COLOR_ATTRIB3 tile mode 9) are rendered into, instead of refused. They use the standard element order of the 4 KiB mode extended by the texture detiler's 64 KiB bits, and are resident like the other tiled targets.

The standard blocks are now wider than tall for 2- and 8-byte elements, as the standard swizzle and the texture layout have them. They were transposed, so texels aliased each other. tests/ColorTargetLayout.cpp checks that every element size and both standard block sizes cover their block exactly once, sized like the texture layout.

Tested

Windows 11 Pro, AMD Ryzen 5 7600, NVIDIA GeForce RTX 5080 (driver 32.0.16.1074), 32 GB, MinGW-w64 GCC 15.2.0.

• GTA V PPSA04264 (01.005) runs with this change on the combined gta-v/testing branch (Performance mode, the prologue).
• On this branch: builds, and ctest passes. Not run here: the relinker's Python tests (my local Python does not find their helper modules) and guest_gameupdate.

Checklist

• Based on current main; no other open PR implements the same functions
• One topic per PR; follow-ups go in a new PR
• No comments in code except technical debt
• Unimplemented paths throw (NotImplemented_nid_no_patch); silent stubs are listed in TechnicalDebt
• No notes, investigation .md files or images added to the repository (attach them to this PR)
• New third-party code is a submodule built from source
• Generic behaviour, not specific to one title
• Depends on: none
• AI-assisted: yes. Written with Claude (Anthropic) under my direction; I reviewed and tested it.

Checked the standard 4 KiB / 64 KiB element offsets and block dimensions against addrlib's 2D SW_4KB_S / SW_64KB_S for 1/2/4/8/16 B elements: all match, including the corrected block orientation. The new tests don't build without the change. Conflicted with main only in RunColorMetadataPass (metadataPassResident now exists); I rebased and applied the != Linear condition inside that helper. Build and ctest green after the rebase; merging once CI is green.
