# Deploy an ALREADY BUILT company website to a web-root directory:
#
#   npx ng build website --base-href /website/
#   projects/website/deploy/deploy.sh /home/moonui/public_html/website moonui
#
# It does not build: /fullpush builds every app first (a failing build blocks the
# merge and every deploy), and this script only installs that artefact.
#
#   1. `assets/config.json` is gitignored and never emitted by the build (only
#      `config.json.example`). The target's own file is kept; a target without one
#      gets `projects/website/src/assets/config.json` (gitignored, per install), else
#      the deploy FAILS — a site without its config shows the config-error screen.
#      moonui: {"apiUrl":"https://moonui.elbaset.com/moon-erp-be/api/website",
#               "defaultLang":"ar","routerBase":"/website/"}
#   2. `.htaccess` is installed from the repo on EVERY deploy — a stale one survives
#      the clean-up forever (storefront 2026-07-22 lesson).
#   3. The root SEO discovery bridge (robots.txt / sitemaps) is refreshed in the
#      parent's .htaccess — a website-only install needs it as much as the store.
#
# The script fails loudly rather than deploying something that cannot boot.
