#!/usr/bin/env bash
# prebuild.sh - Run all prebuild stages before `npm run build`.
#
# Usage:
#   ./prebuild.sh          # run all stages
#   ./prebuild.sh mods     # run only the mods fetch
#
# This script is called automatically by `npm run prebuild`.
# Each stage fetches data from external sources and writes JSON
# to src/data/. The JSON is committed to the repo so builds
# don't depend on external servers.
#
# To add a new prebuild stage:
#   1. Create tools/fetch_<name>.py (or .sh)
#   2. Have it write to src/data/<name>.json
#   3. Add a case block below
#   4. The stage will be called on next prebuild.sh run
