+#
+# scripts/boot.sh — quick direct boot in QEMU (dev loop)
+#
+# Fastest iteration: boots the kernel directly as BOOTX64.EFI via QEMU's
+# FAT driver, skipping the bootloader entirely.
+#
+# Usage:
+#   ./scripts/boot.sh [--gui] [--debug] [--release] [--mem 512M] [--smp 2]
+#
+# Boot chain:  firmware → rsnix (direct)
+# Full chain:  use ./scripts/boot-image.sh (firmware → rsboot → rsnix)
+#
+# Keybindings:
+#   Ctrl-A X   — quit
+#   Ctrl-A C   — QEMU monitor
+#
+# Environment:
+#   OVMF    path to OVMF firmware (default: /usr/share/edk2/x64/OVMF.4m.fd)
+#   MEM     memory size (default: 256M)
+#   SMP     CPU count (default: 1)
+#
