The theme includes powerful per-page settings that allow you to override global Customizer options for individual pages. This gives you full control over the header appearance, menu behavior, dimensions, and more – without affecting the rest of the website.
To access the Page Settings panel:
WordPress Admin → Pages → Edit Any Page
Scroll below the content editor to locate the Page Settings meta box.

These options fully replicate the Customizer settings, with the difference that they override the global header settings for this specific page.
