+# autorender.sh — self-updating nightly render driver for the render rig.
+#
+# Invoked by Windows Task Scheduler (run only when user is logged on):
+#   wsl.exe -d Ubuntu -u glitchhunter -- bash -lc "/home/glitchhunter/Projects/gnommo/autorender.sh"
+#
+# Flow:
+#   1. DEPLOY CODE — git fetch + reset --hard origin/<branch>, then re-exec the
+#      freshly pulled script once. This is how code changes ship from the Mac:
+#      push to origin, and the next run picks them up. SAFE — reset --hard only
+#      rewrites TRACKED files; gitignored project data (video*/) and secrets
+#      (.env) are left untouched. This script NEVER runs `git clean`.
+#   2. RENDER — (pending) `gnommo auto`: per-project down -> gated render -> handoff.
+#
+# Config via environment (set once in ~/.profile / ~/.bash_profile on the rig,
+# so a login shell — bash -lc — picks them up):
+#   GNOMMO_DIR   repo clone on the rig          (default: this script's own dir)
+#   BRANCH       branch to track                (default: main)
+#   NTFY_URL     failure ping endpoint, e.g.    https://ntfy.sh/your-secret-topic
+#
+set -uo pipefail
+
+# Default GNOMMO_DIR to the repo this script lives in, so it works regardless of
+# username or checkout path (rig: /home/glitchhunter/Projects/gnommo).
