- Network block now renders from ETH_*/WIFI_* arrays cached by detect_network() instead of re-running ip/lsusb/iwgetid probes (~210 lines removed, half the subprocesses, no repeated timeouts) - GPU block renders from GPU_DESC/GPU_VERSION cached by detect_gpu() instead of re-parsing lspci and re-running nvidia-smi/dpkg - Extract _lspci_desc() helper (DRY: same sed in 5 places) - Reduce local probe timeouts (ip -4 -o addr, iwgetid) from 2s to 1s - bash -n OK, shellcheck 0 warnings, BATS 36/0, cached renders 15-24x faster
