Install the CirusThaVirus CYD Grok Usage Face pack on this Windows PC.

First, give me a short rundown (what it is, what you will download, where files go, and that flashing needs the BOOT button). Then ask me to confirm. After I confirm, do the work. Do not skip the rundown.

What this is:
- ESP32 Cheap Yellow Display (CYD / ESP32-2432S028) firmware that shows live Grok Bot weekly usage with an animated Grokbot face (pink / baby blue / purple).
- A Windows system-tray app that keeps the USB bridge running and reads live usage from the signed-in Grok Bot install on this PC.
- Printable enclosure STLs for a custom case (in prints/): no supports, 0.16 mm layer height, 5 top / 5 bottom layers, PLA or PLA+.

Download this exact zip (HTTPS):
https://cirusthavirus.com/downloads/free-tools/CYD-Grok-Usage.zip

Install steps after I confirm:
1. Download that zip.
2. Unpack it to the Desktop as a folder named CYD-Grok-Usage (replace that folder if it already exists).
3. Open the prints/ folder and tell me the STL filenames so I can drop them in my slicer.
4. Install Python deps from tools/requirements.txt if needed (pip install -r tools/requirements.txt).
5. If PlatformIO / pio is available, build and flash env cyd to the CYD. Prefer the CH340 COM port. If esptool says wrong boot mode, tell me to hold BOOT and retry.
6. Start the tray app with: pythonw tools/tray_app.py
7. Tell me to right-click the pink tray icon and turn on "Start with Windows" if I want it every boot.
8. Summarize what succeeded, the Desktop path, and any step that still needs me (BOOT hold, missing Grok Bot login, missing STLs).

Rules:
- Do not invent download URLs. Use only the zip above.
- Do not upload, commit, or share sand-secrets, tokens, or usage_cache.json.
- Keep my other files alone. Only create/replace Desktop\CYD-Grok-Usage from that zip.
- If the zip 404s, stop and tell me the site pack is not uploaded yet.
