8# Required:
9#   WHISKERS_ADDR       address to listen on. Bind a private-network address (a VPN), never 0.0.0.0.
10#   WHISKERS_MODEL_URL  the model gateway whiskersd proxies to (an Anthropic Messages API).
11# Optional:
12#   WHISKERS_WRAP       a command prefix that puts the secrets (TYPESAFE_API_KEY and, for the natural voice,
13#                       ELEVENLABS_API_KEY and ELEVENLABS_VOICE_ID) into the environment, e.g.
14#                       "op-env-run -e my-environment --". Unset: they must already be in the environment.
15#   WHISKERS_BIN        the whiskersd binary (default target/release/whiskersd).
