## Simpler model stylesheets

Model stylesheets no longer require you to specify the provider alongside the model. The `llm_model` and `llm_provider` properties have been renamed to `model` and `provider`, and the provider is now auto-inferred from the model catalog — so you can drop `provider` entirely in most cases.

Before:

```css
* { llm_model: claude-opus-4-6; llm_provider: anthropic; }
.gpt { llm_model: gpt-5.2; llm_provider: openai; }
```

After:

```css
* { model: claude-opus-4-6; }
.gpt { model: gpt-5.2; }
```

<Warning>
**Breaking change.** `llm_model` and `llm_provider` stylesheet properties have been renamed to `model` and `provider`. Update your workflow stylesheets.
