- NewOptions.AdminSecret: summer new writes SUMMER_ADMIN__JWT__SECRET
to .env (still 0600), generated from 32 crypto/rand bytes when empty
and validated as at least 32 .env-safe characters
- .env.example gets an empty SUMMER_ADMIN__JWT__SECRET= placeholder
with a comment; the secret never reaches the printed next steps
- The next steps and the generated CLAUDE.md explain the admin at
/backend: make:admin-controller, build, migrate and
summer admin:create --email you@example.com --superuser
- Goldens use a fixed, non-secret admin secret fixture
- Scaffolding, installation and users-and-permissions docs updated
