APP_PORT=3000
# Set to `production` in real deployments. This activates the secret guard that
# refuses to boot with placeholder JWT_SECRET / ADMIN_PASSWORD_HASH values.
# (docker-compose.yml already sets APP_ENV=production for the app service.)
APP_ENV=production

# ── Database ──────────────────────────────────────────────────────────────────
# Set a strong password and keep it in sync between DATABASE_URL and
# POSTGRES_PASSWORD. Generate one with: openssl rand -hex 24

# Connection pool size. Default 10. For a busy event (~100 guests polling the feed

# Admin dashboard password (bcrypt hash).
# Generate with: htpasswd -bnBC 12 "" yourpassword | tr -d ':\n'
# IMPORTANT: keep the SINGLE QUOTES. A bcrypt hash is full of `$` (e.g. $2b$12$…$…),
# and both Docker Compose's env_file interpolation and dotenvy's variable substitution
# would otherwise eat the `$…` segments (reading them as unset vars) and corrupt the
# hash — every admin login then 401s. Single quotes make both read it literally.

# ── Event ─────────────────────────────────────────────────────────────────────
EVENT_NAME=Max & Maria's Wedding

# ── Storage ───────────────────────────────────────────────────────────────────
MEDIA_PATH=/media
# Export archives (Gallery.zip / Memories.zip). MUST be outside MEDIA_PATH —
# /media is publicly served, so exports here would be downloadable without auth.
EXPORT_PATH=/exports

# ── Runtime settings (upload limits, rate limits, capacity) ───────────────────
# NOTE: These are NOT environment variables. Upload size caps, rate limits, guest
# count and quota tolerance are stored in the database `config` table (seeded once
# at first boot) and changed at runtime from the ADMIN DASHBOARD — the backend does
# not read them from .env. Setting them here has no effect. Current seeded defaults:
#   upload rate      100 / hour / guest   (raised from 10 by migration 015)
#   feed rate         60 / minute
#   export rate        3 / day
#   max image size    20 MB
#   max video size   500 MB
#   estimated guests 100
#   quota tolerance  0.75  (fraction of disk that triggers the low-storage warning)
# Adjust these in the admin UI before the event if needed.

# ── Workers ───────────────────────────────────────────────────────────────────
# Number of parallel image/video compression workers. Default 2. This is the main
# throughput bottleneck: with 2 workers a burst of uploads can take ~5s to appear.
# For a large event (100+ guests) 4 is a good target — but each worker can run an
# ffmpeg transcode, so if you raise this ALSO raise the app container's memory limit
# in docker-compose.yml (`app.deploy.resources.limits.memory`) from 1G to ~2G, or a
# burst of large videos can OOM the box and take Postgres down with it.
