Description

• This PR updates the flow diagrams to use yellow-colored boxes for steps where SSPs are required to make minimal changes, as outlined in the Protected Audience API SSP integration guide. The color change visually distinguishes low-effort implementation steps to help developers quickly identify them in the integration workflow.
• It also removes yellow color for the non browser boxes and updates the legend to reflect these changes.

Testing Instructions

• Go to EE PA and check if all SSP boxes have yellow color.
