Server-Side Secret and Resource API Access Control

# Controls whether anonymous API routes may use server-side API keys, CUSTOM_API_*, write APIs, or server resources
# disabled: default. Allow request-provided API keys only; reject server secrets and protected server resources
# protected: require Authorization: Bearer AITUBERKIT_SERVER_SECRET_TOKEN
# demo: allow browser requests from allowed origins / same-origin only. Also require a demo token when AITUBERKIT_DEMO_ACCESS_TOKEN is set; pair with rate limits
# unprotected: legacy compatibility. Not recommended for public URLs

APIs that use server-side secrets or resources, such as CUSTOM_API_*, server-side API keys, chat log saving, VOICEVOX/AivisSpeech server URLs, and speaker-list updates, are controlled by these settings. When deploying to a public URL, explicitly choose at least one of disabled, protected, or demo. If users provide their own API keys in the browser settings, this setting usually requires no additional action.
