PR review (#371): scope the self-host baseline to envs that make sense
without reselling Plunk.
docker-compose.yml: pass through only DISABLE_SIGNUPS (private/single-
admin self-host) and EMAIL_RATE_LIMIT_PER_SECOND (works around the
silent 14/sec fallback when ses:GetSendQuota is denied). Drop the
VERIFY_EMAIL_ON_SIGNUP and OPENROUTER_API_KEY passthroughs — signup
hygiene and phishing detection are reselling concerns.
.env.self-host.example: drop the entire Stripe Billing block (billing
only matters when reselling), drop the VERIFY_EMAIL_ON_SIGNUP doc
block for the same reason, and add an EMAIL_RATE_LIMIT_PER_SECOND
section explaining the silent-14/sec fallback so operators know why
they'd set it.
