"""baseline schema

Revision ID: c6af106a04da
Revises:
Create Date: 2026-07-15 08:21:07.450350

This is the initial baseline. It creates the current schema on a fresh database,
and safely ADOPTS an existing database (one whose tables were created by the old
`Base.metadata.create_all()` before Alembic was introduced): if the schema is
already present it records this revision without recreating anything. That means
`alembic upgrade head` is safe to run on both new and existing deployments — no
manual `alembic stamp` step required.
