<context>
Infrastructure is managed with OpenTofu using the Cloudflare provider. Configuration lives in `infra/`. The D1 database must be provisioned before the Worker can bind to it — OpenTofu handles this automatically via the attribute reference in the Worker resource (see triage 07cafb).

Triage 5c0c64 resolved: schema is applied via `wrangler d1 execute quotesdb --file infra/schema.sql --remote` as a separate step after `tofu apply`. Do NOT use `null_resource` local-exec.
</context>

<goal>
Define the Cloudflare D1 database resource in `infra/d1.tf`.
</goal>

<implementation>
```hcl
# infra/d1.tf

# Cloudflare D1 database for the quotesdb application.
# SQLite-compatible, bound to the API Worker under the binding name "DB".
resource "cloudflare_d1_database" "db" {
  account_id = var.cloudflare_account_id
  name       = "quotesdb"
}

# Export the D1 database ID so it can be referenced in worker.tf and
# used as an argument to `wrangler d1 execute` for schema migrations.
output "d1_database_id" {
  description = "D1 database ID — referenced by the Worker binding and schema migration commands."
  value       = cloudflare_d1_database.db.id
}
```
</implementation>

<notes>
- `cloudflare_d1_database` outputs `id` (String) — the identifier used in Worker bindings.
- The binding name `"DB"` must match what the workers-rs code uses to access the database (set in the API source, not here).
- After `tofu apply`, apply the schema: `wrangler d1 execute quotesdb --file infra/schema.sql --remote` (see ticket bb1514 for schema.sql).
- The D1 ID showing as `(known after apply)` in `tofu plan` is expected; the Worker binding resolves it at apply time automatically.

<validation>
Run from the `infra/` directory:

```sh

tofu plan
```
