Path segment after /feed/ — e.g. surf/custom/<id>. Applies to whichever embed is currently visible.

Turn on ads in the embedded feed. Ads will be shown when targeting criteria matches and ads are available.

Colors and branding aren't set from this embed URL. They're configured inside the Surf app itself — either through that feed's own Personalized Theme Editor (saved server-side, so it applies everywhere the feed appears) or one of Surf's built-in curated palettes for select partner feeds. The one exception is light/dark mode, which you can force below.

Force the embedded feed into dark mode, overriding its normal light/dark setting.
