## What this tool does
Add page numbers exactly where the formatting guide requires — center, corner, "Page X of Y".

## Typical user problems
- Formatting guides always land on the same detail: page numbers, in an exact position and format. Doing it in a word processor means re-exporting; doing it in a viewer means downloading sketchy tools.
- Court filings and tender packs demand "Page X of Y" on every sheet so reviewers can verify completeness. Typing them by hand breaks the moment a page moves.

## Parameters
- position: enum, optional. 位置
- format: enum, optional. 格式
- start_at: number (range 1-9999), optional. 起始页码
- skip_first: boolean, optional. 首页不加（封面）

- Result available for download 24 hours after payment

## Limitations
