You are helping me build the following AI agent workflow.

## Goal
Website Screenshot Capture: Automatically captures headless screenshots of protected websites using Bright Data Web Unlocker and saves the PNG to your local disk.

## Specification
- What it does: Capture protected website screenshots instantly by bypassing anti-bot defenses like Cloudflare with Bright Data Web Unlocker. You get the resulting PNG images saved directly to your local disk without needing a manual browser session.
- Trigger: Run manually (Manual · on demand)
- Autonomy: Fully hands-off
- Expected setup effort: about an afternoon
- Tools/services involved:
  - Bright Data Web Unlocker: Bypass anti-bot protections to capture screenshots
  - HTTP Request: Send API request to Bright Data
  - Write a file to disk: Save captured screenshot image locally

## Known pitfalls, handle each one explicitly in your implementation
1. Large response bodies from high-resolution screenshots can exceed memory limits so implement streaming writes to disk instead of loading into RAM.
2. Anti-bot systems may block your IP if requests come too frequently so add a random delay between captures to mimic human behavior.
3. File permissions on the target directory might prevent writing so verify write access before starting the automated batch process.

## Reference implementation
https://n8n.io/workflows/3465 (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.
