🎨 New header logo design - Refreshed ASCII art banner (thanks @naxci1)
🧹 Remove dead flash attention wrapper - Removed legacy code from FP8CompatibleDiT; FlashAttentionVarlen already handles backend switching via its attention_mode attribute
🛡️ Fix graceful fallback from flash-attn - Add compatibility shims for corrupted flash_attn/xformers DLLs, preventing startup crashes when CUDA extensions are broken
📊 Improved VRAM tracking - Separate allocated vs reserved memory tracking, Windows-only overflow detection (WDDM paging behavior)
♻️ Centralize backend detection - Unified is_mps_available(), is_cuda_available(), get_gpu_backend() helpers across codebase
🔄 Revert 2.5.14 VRAM limit enforcement - Removed set_per_process_memory_fraction call; Overflow detection and warnings remain.
