clay v0.14 (deps/clay, zlib licence) supplies the layout engine for the new akgl_ui subsystem. Sources-listed rather than add_subdirectory()'d, on the semver/libccd precedent: clay's CMakeLists declares no library target, builds its examples by default, and requires CMake 3.27 against this project's 3.10. src/ui_clay.c is the one CLAY_IMPLEMENTATION translation unit, compiled -w on the vendored-code terms but with clay's symbols deliberately exported -- consumers' CLAY() macros resolve against libakgl.so, and akgl/ui.h warns them never to link a second clay. The subsystem is runtime-optional the way collision is: always compiled in, inert until akgl_ui_init(), which bounds clay to the overridable AKGL_UI_* ceilings, checks Clay_MinMemorySize() against a static BSS arena (no malloc), and refuses with both numbers in the message when it does not fit. Measured: 812544 bytes at the default 1024 elements / 4096 measured words, against a 1 MiB arena. clay's void-callback layout errors are logged as they happen and the first is stashed for the error protocol to raise later. AKGL_ERR_UI joins the status band before AKGL_ERR_LIMIT, named in akgl_error_init. New `ui` test suite covers validation, the init/shutdown lifecycle, and arena exhaustion via the akgl_ui_arena_limit test hook (same contract as akgl_ccd_arena_set_limit). clay.h is installed beside semver.h, its licence beside libccd's, and the headers suite proves akgl/ui.h self-contained -- clay.h compiles clean under -Wall.
