+/**
+ * This script changes prices for existing Recurly subscriptions.
+ * It schedules changes to apply at the next renewal.
+ *
+ * Usage:
+ *   node scripts/recurly/change_existing_subscription_prices.mjs [OPTS] [INPUT-FILE]
+ *
+ * Options:
+ *   --timeframe TIMEFRAME  Either 'renewal' or 'now' (default: renewal)
+ *   --output PATH          Output file path (default: /tmp/change_prices_output_<timestamp>.csv)
+ *                          Use '-' to write to stdout
+ *   --commit               Apply changes (without this flag, runs in dry-run mode)
+ *   --throttle DURATION    Minimum time (in ms) between subscriptions processed (default: 2400)
+ *   --force                Overwrite any existing pending changes
+ *   --help                 Show a help message
+ *
+ * CSV Input Format:
+ *   The CSV must have the following columns:
+ *   - subscription_uuid: Recurly subscription UUID
+ *   - plan_code: Current plan code
+ *   - currency: Current currency
+ *   - unit_amount: Current price per unit
+ *   - new_unit_amount: New price per unit
+ *   - subscription_add_on_unit_amount_in_cents: Current additional-licenses add-on price (optional)
+ *   - new_subscription_add_on_unit_amount_in_cents: New additional-licenses add-on price (optional)
+ *
+ * Output:
+ *   Writes a CSV with columns:
+ *   - subscription_uuid: The subscription UUID processed
+ *   - status: Result status (changed, validated, not-found, inactive, mismatch, pending-change, or error)
+ *   - note: Additional information about the status (includes dry run notice when not using --commit)
+ *
+ * Running on a Pod:
+ *   This script may run for multiple days. When running using `rake run:longpod[ENV,web]`,
+ *   use one of these strategies to preserve output:
+ *
+ *   1. Tail the output file from another session (the filename is logged when the script starts):
+ *      kubectl exec -it <pod-name> -- tail -f /tmp/change_prices_output_<timestamp>.csv > local_backup.csv
+ *
+ *   2. Periodically copy the output file to your laptop:
+ *      kubectl cp <pod-name>:/tmp/change_prices_output_<timestamp>.csv ./backup.csv
+ *
+ *   3. Write to stdout and capture locally:
+ *      kubectl exec -it <pod-name> -- node scripts/recurly/change_existing_subscription_prices.mjs \
+ *        --timeframe renewal --commit --output - input.csv > output.csv
+ *
+ *   For monitoring handoffs, have the next person start tailing (or copying periodically)
+ *   before the current monitor disconnects to ensure no records are lost.
