+# DarkForge Linux — Phase 0: Full Bootstrap
+# ============================================================================
+# Purpose:  Single entry point that runs the entire Phase 0 bootstrap:
+#           1. Tear down & create fresh loopback filesystem
+#           2. Set up directory structure, lfs user, env files
+#           3. Download source tarballs
+#           4. Copy toolchain scripts to $LFS so lfs user can access them
+#           5. Launch build-all.sh as the lfs user
+#
+# Usage:    sudo -E bash toolchain/bootstrap.sh
+#           (run from the project root, e.g. /home/danny/darkforge)
+#
+# Inputs:   LFS (default: /mnt/darkforge)
+# Outputs:  A complete cross-toolchain and temporary tools on $LFS
+# Assumes:  Running as root on Arch Linux, internet access
+# ============================================================================
