- USE_VBO_GRID: never defined (SF_GRID deliberately off VBO path per tr_local.h); remove dead grid VBO estimate/queue/pack paths in vk_vbo.c and tr_surface.c. - USE_TESS_NEEDS_NORMAL / USE_TESS_NEEDS_ST2: commented-out defines with no struct fields; remove preprocessor guards that only wrapped always-on paths. - USE_VK_PBR dead #else: unwrap non-PBR shader module init/destroy fallbacks in vk_shader_modules.c and vk_shutdown.c; flatten VK_CUBEMAP/VK_PBR_BRDFLUT nesting in tr_local.h; unwrap reactive/object-id storage descriptor (void)0 else stubs. - USE_DEDICATED_ALLOCATION: always defined in vk.h; drop redundant #ifndef override in vk_instance.c. Behavior unchanged on the active PBR/VBO/dedicated-allocation paths. Co-authored-by: Tim Fox <timfox@outlook.com>
USE_VK_PBR is unconditionally defined in tr_local.h for the Vulkan renderer. Remove non-PBR #else fallbacks in pipeline creation, vertex layout, descriptor counts, and BSP/surface helpers while keeping shader templates and runtime vk.pbrActive gating intact. Adds scripts/tools/unwrap_use_vk_pbr.py for future cleanups. Co-authored-by: Tim Fox <timfox@outlook.com>

Summary
Reduce Vulkan renderer technical debt by removing compile-time feature flags that are permanently on/off and deleting their dead
#elsebranches. Behavior on the active paths is unchanged.Branch:
