# 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.
