Mobile logo
Separate header logo and max width / padding for small screens.
Mobile logo
Optional logo for smaller viewports, with its own max width and padding.
Where to find it
Admin → Settings → Settings (first tab) → Branding → Mobile logo
Upload: logo_mobile
Sizing: logo_mobile_max_width_px (default often 144), logo_mobile_padding (+ sides). Same note as desktop: margin keys are not in the Branding UI.
How it works
Keep a wide wordmark on desktop and a compact mark on phones so the menu still fits. If you skip the mobile upload, the theme usually falls back to the menu logo.
Common problems
Desktop fine, phone looks broken
Upload a dedicated mobile asset and a smaller max width.
