# God's Eye View — environment variables
# Copy to .env and fill in your keys. On macOS the launcher can also read keys
# from the Keychain (see README); on Linux/Windows use this file or env vars.
#
# Easiest path: don't edit anything. Run the app and paste keys into the
# in-app Provider Settings panel (the POWER UP chip, bottom-right) — it writes
# this checkout's .env for you (owner-only permissions) and restarts the dev
# server. Under the Pinokio launcher it writes pinokio/ENVIRONMENT instead.
# Keys you supply yourself (shell env, Keychain) are shown as configured
# externally and never touched. This file remains the reference for headless
# and self-hosted setups.
#
# NOTE ON CLIENT-EXPOSED KEYS: GOOGLE_MAPS_API_KEY and CESIUM_ION_TOKEN are
# injected into the browser bundle by design (they're used client-side) and
# WILL be visible in devtools. Restrict/scope them rather than trying to hide
# them (see SECURITY.md). All other keys below stay server-side.

# Optional: direct Google Photorealistic 3D Tiles and GEV place search.
# Without it, a Cesium ion token can still load ion-hosted Google 3D; with
# neither credential, the app starts on keyless Esri World Imagery with OSM
# available in the map tray and as the automatic provider-failure fallback.
# CLIENT-EXPOSED — restrict it (HTTP referrer + API restriction) in Google Cloud.
GOOGLE_MAPS_API_KEY=
# Optional: opt-in per-IP rate limit for the Google Places cost endpoint
# (/api/google/nearby-places), in requests per minute.
# DEFAULT IS UNLIMITED — unset (or 0) means no throttling, unchanged behavior.
# Set a positive integer to cap per-IP Places quota spend when self-hosting.
# Recommended whenever HOST is not localhost. NOTE: this is a per-IP,
# process-local guard (in-memory, resets on restart; over-limit requests get a
# sanitized 429) — it is NOT a billing cap. For hard spend protection set
# provider-side budget alerts: Google Cloud Console -> Billing -> Budgets & alerts
# (plus per-API quotas under APIs & Services -> Quotas).
# GEV_RATELIMIT_GOOGLE_PER_MIN=60

# Optional: Google Photorealistic 3D Tiles through Cesium ion, Bing world
# imagery, and Cesium World Terrain. The free Community plan is for eligible
# personal/non-commercial use and has quotas; check current Cesium terms. A
# direct Google key above is still required for GEV place search.
# CLIENT-EXPOSED — use a public assets:read token with URL restrictions.

# Optional: OpenAI Realtime voice control. Do not prefix with VITE_.
OPENAI_API_KEY=
OPENAI_REALTIME_MODEL=gpt-realtime-2

# Optional: opt-in per-IP rate limit for the OpenAI cost endpoints
# (/api/realtime/token + /api/openai/hud-summary), in requests per minute.
# DEFAULT IS UNLIMITED — unset (or 0) means no throttling, unchanged behavior.
# Set a positive integer to cap per-IP spend when self-hosting on a network.
# Recommended whenever HOST is not localhost. NOTE: this is a per-IP,

# provider-side budget: OpenAI platform -> Settings -> Limits (usage limits).
# GEV_RATELIMIT_OPENAI_PER_MIN=30

# Optional: OpenSky auth mode (oauth | basic | auto | anon)
# Default: oauth — requires client credentials below
# Set to "anon" to skip aircraft auth (rate-limited but works)
OPENSKY_AUTH_MODE=oauth

# Optional: OpenSky OAuth credentials (from opensky-network.org account dashboard)

# Optional: dev server config
PORT=4173
# Network binding. Default is localhost — the server is reachable ONLY from
# this machine. This is the safe default: the dev server brokers your
# configured API keys, so anyone who can reach it can spend your quota.
# LAN opt-in: set HOST=0.0.0.0 to share on your local network. WARNING: that
# exposes every key-brokering proxy to everyone on the network — use only on
# networks you trust, and consider the GEV_RATELIMIT_* throttles above.
# HOST=localhost
# HOST=0.0.0.0

# Optional: NASA FIRMS live active fires. SERVER-SIDE ONLY (never reaches the
# browser — the client polls the /api/firms proxy). Free key:
# https://firms.modaps.eosdis.nasa.gov/api/map_key/
# Without a key the FIRMS Active Fires layer is empty ("KEY REQUIRED").

# Optional: Live AIS vessels layer
# Browser fetch path. Keep same-origin so the private stream key stays server-side.

# Client render cap. The server can keep a larger AISStream cache, but drawing
# every global vessel at once can overwhelm WebGL on laptops.

# Feed watchdog: silence (ms) after which the feed is REPORTED stale; the socket
# is recycled at 2.5x that. Default 120000. The watchdog self-arms only for the

# quiet, so set this explicitly (sized for your filter) to opt back in.
# 0 disables the silence watch entirely.
# AISSTREAM_SILENCE_TIMEOUT_MS=120000

# Optional: TomTom live traffic flow (BYOK freemium — free tier is ~50,000 tile
# requests/day, get a key at https://developer.tomtom.com). SERVER-SIDE ONLY:
# the browser fetches same-origin /api/tomtom/* and never sees the key.
# Keyless fallback: the traffic layer runs its built-in simulation (white dots,
# hardcoded per-road-class speeds) — no key required for the layer to work.
# TOMTOM_API_KEY=
# Optional soft cap on upstream tile fetches per UTC day (default 40000) — a
# configurable application safety ceiling, not a guarantee of staying within
# TomTom's free allowance (currently 200K tile requests/month:
# https://docs.tomtom.com/pricing/). Over the cap the proxy serves cached/stale
# tiles instead of hitting upstream.
# TOMTOM_DAILY_TILE_BUDGET=40000

# unless you're customizing the camera source pack.
