# Required: Get your API key from https://resend.com/api-keys
RESEND_API_KEY=re_your_api_key_here

# Required in production: sender address for the contact form.
# Must be a verified domain in Resend. If unset, the contact route will 500 in production.
# RESEND_FROM_EMAIL=contact@zachlamb.com

# Optional: Where the contact form forwards messages (backend-only, never shown
# to visitors). Defaults to zachlamb94@gmail.com. Override in Vercel if you want
# submissions to go elsewhere.
# CONTACT_EMAIL=zachlamb94@gmail.com

# Optional: Public-facing mailto address shown in "Or reach out directly".
# Distinct from CONTACT_EMAIL — this is the alias visitors see. If unset, falls
# back to you@zachlamb.io.
# NEXT_PUBLIC_CONTACT_EMAIL=you@zachlamb.io

# Optional: Sentry error tracking. Without these, Sentry is a no-op.
# Get DSN from https://sentry.io/settings/<org>/projects/<project>/keys/
# NEXT_PUBLIC_SENTRY_DSN is exposed to the client so it can report errors.

# Optional: Upstash Redis for cross-instance contact-form rate limiting.
# Without these, rate limiting falls back to an in-memory Map that's per-
# lambda-instance (effective cap = N_warm x 5). Set in Vercel for prod:
#   https://console.upstash.com -> create a REST database.
