"""
sync_cutscene_translations.py - Sync a cutscene config's strings into a translation file.

Reads <cutscene_config.json>, collects every non-empty "speaker" and "text" string
from its lines, and appends any string not already present as a "key" in
<translations.json> as a new entry with an empty "en" slot ready for a translator
to fill in. New entries are always appended at the end of the list so missing
translations are easy to locate.

Cutscene translations are intentionally kept in their own file/database, separate
from dialogue translations - point <translations.json> at a dedicated file such as
resources/dialogue/cutscene_translations.json.

Usage:
    python sync_cutscene_translations.py <cutscene_config.json> <translations.json>
