      x-ai-role: conversion_optimization_analyst
      x-ai-description: Provides aggregated performance metrics for all pop-up widgets within a project. This is the top-level analytics endpoint — it shows the full funnel from impressions to interactions across every pop-up in the project scope, making it the primary entry point for evaluating overall campaign effectiveness before drilling into individual widget performance.
      x-ai-reasoning-instructions:
      - If no date range is specified, clarify with the user whether they want all-time data or a specific period, as unbounded queries may return large datasets.
      - Validate that `projectId` is a valid UUID before calling — malformed IDs return a 400 with a specific error message.
      - When interpreting results, calculate the interaction rate (interactions / impressions) to give the user a meaningful conversion metric, not just raw counts.
      - If the result array is empty, check whether the project has any published pop-ups or whether the date range predates their creation.
      x-ai-responding-instructions:
      - Summarize the aggregate impression and interaction counts across all pop-ups, then highlight the overall interaction rate as a percentage.
      - If the date range was specified, frame the results in that context (e.g., 'Over the past 30 days...').
      - Suggest drilling into individual widget statistics as a logical next step if the project contains multiple pop-ups.
      - On a 404, confirm whether the projectId is correct and whether the user has access to that project.
      x-ai-suggestions:
      - 'Use Unix timestamps for `start` and `end` — e.g., last 30 days: start=now-30d, end=now.'
      - Combine with individual widget endpoints to compare top-performing pop-ups against the project average.
      - Schedule periodic calls to track conversion rate trends over time.
