# ======================================================
# Workflow: Update Frontend Build
# ======================================================
# This workflow is triggered manually (or via repository_dispatch)
# from your PRIVATE frontend repo after a new build.
#
# Setup:
#   1. In your PRIVATE frontend repo, create a GitHub Action that:
#      - Builds the Vue.js project
#      - Uses repository_dispatch to trigger this workflow
#      - Or: upload the dist as an artifact and trigger this workflow
#
#   2. Create a GitHub Personal Access Token (PAT) with repo access
#      and store it as a secret: FRONTEND_DEPLOY_TOKEN
#
# Alternative: Run manually from the Actions tab.
