+# homepage-render-dev.sh — render jayrup.me locally WITHOUT deploying.
+#
+# Runs the same two-pass render (html + txt) as deploy-docker.sh inside the
+# pinned quarto container, writing output to public/ (gitignored). Use this to
+# preview blog posts / style changes before committing.
+#
+# Usage:
+#   ./homepage-render-dev.sh [repo-dir]        # default: current directory
+#   QUARTO_IMAGE=<image> ./homepage-render-dev.sh   # override the container image
+#
+# Notes:
+#   - The default image digest MUST stay in sync with deploy-docker.sh
+#     (update both deliberately when bumping quarto).
+#   - On voidlaptop, docker needs the docker group: run via `sg docker` or
+#     `DOCKER=(sg docker -c)` wrapper. On other machines plain docker works.
+#   - public/ and .quarto/ are gitignored; nothing here touches origin.
