# ScreenTinker server configuration — process environment variables.
#
# NOTE: the app reads these from the *process environment* (your systemd unit's
# Environment=/EnvironmentFile=, your container runtime, or your shell). It does
# NOT auto-load this file. Copy the values you need into your process manager.
# This file exists only to document the available options.

# --- Self-hosting ---
# Set to "true" on your own instance. When true, the hosted signup emails
# (welcome to the user + admin notification) are disabled, so a self-hosted
# instance never emits mail from a domain that isn't yours.
SELF_HOSTED=true

# Close public self-service registration — for instances where all accounts are
# provisioned by your team (admin "Add user" / invites). When true, the public
# signup route is blocked (OAuth auto-signup with it) AND the login page hides
# its "Create account" button so the UI matches the backend. First-user setup on
# an empty DB is still allowed so a fresh install can be initialized.
# DISABLE_REGISTRATION=true

# Redirect "/" to the app (/app) instead of serving the marketing landing page.
# For internal-only deployments that don't want the public homepage shown.
# DISABLE_HOMEPAGE=true

# Where new-signup admin notifications are sent. Leave UNSET to disable admin
# notifications entirely — the user's welcome email is unaffected. Self-hosters
# who want to be notified of signups set this to their own address.
# ADMIN_NOTIFY_EMAIL=you@example.com

# Marks THIS deployment as the hosted (screentinker.com) instance. Gates the
# daily activation-nudge sweep (the T+3 "haven't paired a screen yet?" email).
# Leave UNSET on self-hosted instances so a daily bulk sweep never emails your
# user base with our onboarding mail. Only the hosted instance sets this true.
# HOSTED_INSTANCE=true

# --- Outbound email (Microsoft Graph, client-credentials flow) ---
# Required for ANY email (welcome, offline alerts, admin notify) to actually
# send. Leave blank and the app logs "[EMAIL] not configured" instead of sending.

# Dev safety net: comma-separated allow-list of recipients. When set, mail to
# any address NOT in the list is suppressed (logged, not sent). Leave UNSET in
# production. Useful locally so test signups can't email real users.
