# Safe server build for RMS 007 (Next.js + Prisma + MySQL).
# Does NOT use system Node — only the portable cache under this project (same pattern
# as office invoicing/scripts/build-provider.sh).
#
# From project root:
#   chmod +x scripts/build-rms.sh
#   ./scripts/build-rms.sh
#
# Optional env:
#   NODE_VERSION=20.19.3                      (default)
#   NODE_PORTABLE_CACHE=$PWD/.node-portable-cache
#   SKIP_PRISMA=1                             skip migrate + seed (build only)
#   SKIP_BUILD=1                              only install + prisma
#
# cPanel (Setup Node.js App):
#   Application root: /home/iseekhelpinterna/rms.iseekhelpinternational.com
#   Application URL: rms.iseekhelpinternational.com
#   Application startup file: server.js   ← project root server.js (not .next/…)
#   Node.js version: 20.x
#   Environment: DATABASE_URL, JWT_SECRET, OFFICE_API_BASE, RMS_LINK_TOKEN,
#                NODE_ENV=production (and GEMINI_API_KEY if needed).
#   cPanel rewrites .htaccess so traffic hits Node — without this you only see
#   an Apache directory listing ("Index of /").
