## Move policy packs to policy rules

v2 policy packs become policy rules, and `policyPackPresets` becomes
`policyRulePresets`, exported from `c15t`. Where the rules live depends on your
backend:

* **Inth**: set the rules in your Inth project. Rules in client code do not
  change a hosted policy.
* **Self-hosted**: move the backend's `policyPacks` to `manifest.policyRules`.
  See [policy configuration](/docs/self-host/guides/policy-packs).
* **Offline**: move `offlinePolicy.policyPacks` to `offline({ policyRules })`.

```tsx title="After (v3): offline policy rules"
import { offline, policyRulePresets } from 'c15t';

const mode = offline({
	policyRules: [
		policyRulePresets.europeOptIn(),
		policyRulePresets.worldOptOutNoPrompt(),
	],
});
```

In Next.js, import `offline` from `c15t/next` instead and set the result as
`mode` in `c15t.config.ts`. Both take the same `policyRules`.

|v2 preset|v3 preset|
|--|--|
|`europeOptIn()`, `europeIab()`|Same names|
|`californiaOptIn()`, `californiaOptOut()`|Same names|
|`quebecOptIn()`|Same name|
|`worldNoBanner()`|`worldOptOutNoPrompt()`|

`worldNone()` is a separate, new preset: it shows nothing and grants no
rights, while `worldOptOutNoPrompt()` keeps v2's opt-out and preference rights.

The `policy-packs-to-policy-rules` codemod renames `policyPackPresets` and
`worldNoBanner()`, and moves the import to `c15t` where it came from
`c15t/react` or `c15t/next`. `consent-provider-options` moves
`offlinePolicy.policyPacks` into `offline({ policyRules })`. Preset calls need
no other change, but a hand-written v2 pack uses `consent` and `ui` keys,
which v3 rules replace with flat keys such as `model` and `prompt`; the
codemods mark those with a `TODO(c15t v3)` comment.

v3 adds presets for more regions. `offline()` without `policyRules` uses
`recommendedPolicyRules()`. Read [policies](/docs/concepts/policies) before you
change a rule's model or prompt, and
[how consent works](/docs/concepts/how-consent-works) for the difference
between a permission and a recorded choice.
