#15529 a509941 Thanks @florian-lefebvre! - Adds a new build-in font provider npm to access fonts installed as NPM packages

You can now add web fonts specified in your package.json through Astro's type-safe Fonts API. The npm font provider allows you to add fonts either from locally installed packages in node_modules or from a CDN.

Set fontProviders.npm() as your fonts provider along with the required name and cssVariable values, and add options as needed:
```
import { defineConfig, fontProviders } from 'astro/config';

export default defineConfig({
  experimental: {
    fonts: [
      {
        name: 'Roboto',
        provider: fontProviders.npm(),
        cssVariable: '--font-roboto',
      },
    ],
  },
});
```
See the NPM font provider reference documentation for more details.
#15548 5b8f573 Thanks @florian-lefebvre! - Adds a new optional embeddedLangs prop to the <Code /> component to support languages beyond the primary lang

This allows, for example, highlighting .vue files with a <script setup lang="tsx"> block correctly:
```
---
import { Code } from 'astro:components';

const code = `
<script setup lang="tsx">
const Text = ({ text }: { text: string }) => <div>{text}</div>;
</script>

<template>
  <Text text="hello world" />
</template>`;
---

<Code {code} lang="vue" embeddedLangs={['tsx']} />
```
See the <Code /> component documentation for more details.
#15483 7be3308 Thanks @florian-lefebvre! - Adds streaming option to the createApp() function in the Adapter API, mirroring the same functionality available when creating a new App instance

An adapter's createApp() function now accepts streaming (defaults to true) as an option. HTML streaming breaks a document into chunks to send over the network and render on the page in order. This normally results in visitors seeing your HTML as fast as possible but factors such as network conditions and waiting for data fetches can block page rendering.

HTML streaming helps with performance and generally provides a better visitor experience. In most cases, disabling streaming is not recommended.

However, when you need to disable HTML streaming (e.g. your host only supports non-streamed HTML caching at the CDN level), you can opt out of the default behavior by passing streaming: false to createApp():
```
import { createApp } from 'astro/app/entrypoint';

const app = createApp({ streaming: false });
```
See more about the createApp() function in the Adapter API reference.
