# A brief for one public-page performance change

Replace the bracketed details. This is a proposed task, not a measured result.

```text
Improve [one public page] for [the reader’s main task].
First list its controls, required assets, and signed-in differences.
Record the current page, viewport, browser, network and CPU settings.
Measure selected asset bodies separately from whole-page transfer.

Propose one dependency change and explain what behavior it preserves.
Keep content, account gates, tracking and required controls intact.
Do not change payments, create accounts or send external messages.

Repeat comparable loads and retain every result, including slower runs.
Check menu, theme, keyboard access, copy/download, and navigation both ways.
Report observed differences, failures, setup and anything not tested.
Do not claim a production, search or signup improvement from local results.
```
