You are helping me build the following AI agent workflow.

## Goal
ClickUp Time Tracking & Performance Reports: Daily digest of task logs, time estimates vs actuals, overdue alerts, and performance metrics sent via email.

## Specification
- What it does: Get a daily email digest of your task logs, time estimates versus actuals, overdue alerts, and performance metrics directly from ClickUp. You receive these polished reports in your Gmail inbox so you can instantly see how your team is performing without manual checks.
- Trigger: On a schedule (Scheduled · daily 9:00 AM)
- Autonomy: Fully hands-off
- Expected setup effort: about an afternoon
- Tools/services involved:
  - ClickUp: Retrieve tasks, time logs, and performance data
  - Gmail: Deliver HTML reports to stakeholders
  - Code: Process data and generate report content

## Known pitfalls, handle each one explicitly in your implementation
1. HTML emails often strip external stylesheets, so inline all CSS properties directly into the HTML tags.
2. Time zone mismatches between ClickUp logs and your processing server can skew daily metrics, so normalize timestamps to UTC before aggregation.
3. Sensitive assignee data might be exposed if recipients are not strictly validated against an allowlist.

## Reference implementation
https://n8n.io/workflows/7570 (workflow template)
Fetch and inspect this before building. If it matches my stack, adapt it;
if not, rebuild the pattern with my tools.

## Process requirements
1. Before building: ask me which of the listed tools I actually use and
   what my platform is (n8n / Make / code / other). Do not assume.
2. Adapt the pattern to my answers; do not force the reference stack.
3. Address every pitfall above; tell me how you handled each.
4. Provide a test plan I can run before letting this touch real data.
5. Ask before any step that sends messages, modifies data, or spends money.
