+# deploy-artifact-to-eric-turner.sh
+#
+# Deploy the Signal & Noise interactive HTML artifact to the eric-turner.com
+# Hugo site, then force Hugo to pick up the change by touching hugo.yaml.
+#
+# Why touch hugo.yaml? Hugo runs as `hugo server --poll 1s` in a Docker
+# bind-mount. The poll watcher detects changes in the top-level file tree
+# reliably, but NEW subdirectories under static/ (added via scp after the
+# server started) don't always get picked up by the watcher's in-memory
+# state. The config-file watch is more reliable — touching hugo.yaml
+# triggers a full rebuild, which re-reads all static/ subdirectories and
+# invalidates any stale file cache.
+#
+# This is the durable fix for the "I scp'd the file but the live URL still
+# shows the old version" problem we hit twice. Always use this script
+# (or `touch hugo.yaml` after any manual scp) instead of raw scp.
+#
+# Usage:
+#   bash scripts/deploy-artifact-to-eric-turner.sh
+#   bash scripts/deploy-artifact-to-eric-turner.sh --verify
+#
+# Requires SSH access to root@10.13.0.254 and Hugo running in
+# /mnt/user/docker/showcase.
