Repro steps
- 1.Open the splash landing page / at a 390x720 mobile viewport.
- 2.Look at the header. Only the starlight logo and the search icon are shown.

- 5.Press Escape to close the menu.
- 6.Navigate back to / and check the header again. There is still no menu button.
Expected
The splash landing page header shows a mobile menu button at small viewports, like /getting-started does, so mobile users can reach the theme toggle and social links.
Actual
The splash page header shows only the logo and the search icon. It has no menu button, so mobile users cannot reach the theme toggle or social links. A console warning at 35.1s reads 'Splash page hamburger visible: false'.

## Summary On the splash-template landing page (`/`), the mobile header has no menu button at a 390px viewport. The theme toggle and social links are therefore not reachable on mobile. Doc pages such as `/getting-started` show the menu button and it works. ## Environment - Chromium 151.0.7922.34, macOS - Viewport 390x720, DPR 2 - Starlight v0.42.x (per report title) ## Steps to reproduce 1. Open `/` at a 390x720 viewport (0.0s). 2. Look at the header. Only the logo and the search icon are shown (3.0s). 3. Scroll down and back up. No menu button appears (8.4s to 10.2s). 4. Control: open `/getting-started` and click the `menu` button (20.0s). The sidebar opens (21.0s). 5. Press Escape (24.3s), then return to `/` (25.4s). There is still no menu button (27.0s to 39.0s). ## Expected The splash page shows a mobile menu button, so users can reach the theme toggle and social links. ## Actual The splash page header has only the logo and the search icon.
