Clay's debug inspector (Clay__RenderDebugView, ~700 lines + ~150 UI strings) is reachable from the exported Clay_EndLayout behind runtime debugModeEnabled branches, so --gc-sections can't drop it; at -O2 clang inlines it into the layout monolith. clayterm never enables debug mode, so it's dead weight. Adds an upstream-compatible CLAY_DEBUG_MODE_ENABLED value macro (default 1; patches/clay-debug-mode-enabled.patch), named to match the runtime context->debugModeEnabled selector. Generated against the submodule's recorded commit (938967a) and covering all four debugModeEnabled sites; opted out via -DCLAY_DEBUG_MODE_ENABLED=0. The Makefile now applies Clay patches generically: every patches/*.patch is applied (in sorted order) after resetting clay/clay.h to pristine, so the applied set always matches the directory exactly and future patches (e.g. #115's grow-minDimensions fix) need no per-patch Makefile wiring. Reverted by make clean. Drop individual patches as they ship upstream. raw wasm 155,877 -> 101,208 (-35.1%); brotli 44,141 -> 29,133. Cold path only (debugModeEnabled always false at runtime); deno task test test/ passes (19 files, 227 steps).
