name: Set Up Blog

# Run this workflow to configure your blog's optional integrations.
# It stores your settings as GitHub Actions repository Variables
# (never committed to source) so every fork starts clean.
#
# How to run:
#   Go to Actions → "Set Up Blog" → Run workflow → fill in the inputs → Run.
#   The workflow sets the variables and then the next build picks them up.
#
# Prerequisites (one-time, takes ~30 seconds):
#   Go to Settings → Actions → General → Workflow permissions and select
#   "Read and write permissions". This lets the default GITHUB_TOKEN create
#   repository variables — no personal access token needed.
