# Heroku container build manifest.

#
# Used with the "Deploy to Heroku" button together with app.json. The Dockerfile
# needs CGO for SQLite, so this builds from the repo's top-level Dockerfile
# instead of using Heroku buildpacks.
#
# Heroku dynos have an ephemeral filesystem, so SQLite state under /tmp is lost
# on every restart. For a durable deploy, use Render or Railway, or attach
# external storage (e.g. a Heroku Postgres add-on + a DB backend port).
