a6c032d824- KDE thumbnailer: texture loader, decodes only the mip it needs; GPU blocks, 16-bit and float via the new yapf_tex_to_rgba8. Tested through KDE's plugin loader with KF6 from nixpkgs. - Photoshop: shows the tool's error message; HDR textures open as 32-bit (.hdr), 16-bit stays 16-bit; 16-bit documents save as 16-bit. - CLI: 16-bit PNG export, readable conversion errors. - default.nix: yapf tool, library, header, MIME type and thumbnailer (absolute store path); runs the test suite.
