Ability to customize siteTitleHref in Logo

[roll]

What version of starlight are you using?

0.35.2

What is your idea?

Currently, it seems to be that the only way to change the link of the Logo is fully "escaping" SiteTitle component (not sure if there is a way to re-use Default)

A new config.logo.href might simplify the things

Why is this feature necessary?

If you have a multi-subdomain project like:

• project.dev
• lang1.project.dev
• lang2.project.dev

It's more natural to have logo linking always to project.dev even from subdomains (currently, it leads to a subdomain root)

Do you have examples of this feature in other projects?

No response

Hi @roll, the easiest way to customise it is using a route middleware currently:

import { defineRouteMiddleware } from '@astrojs/starlight/route-data';

export const onRequest = defineRouteMiddleware((context) => {
  // Set a custom link for the site title
  context.locals.starlightRoute.siteTitleHref = 'https://example.com';
});

(You can also re-use default components in overrides, but the middleware approach is probably still preferable.)

Thanks!
