## FAQ

### Why a ladder rather than one file?

Most size-related bugs only appear at a threshold — an upload cap, a memory limit, a pagination boundary. A ladder crosses every plausible threshold in one pass, so you find the break point instead of guessing at it.

### Can I download them all at once?

Yes. Every set offers a single ZIP containing all 15 files, or you can download any individual step from the list.

### Why are some steps skipped?

The upper steps of a ladder are large enough to be slow to build in a browser tab. The size limit skips them by default, and the result always reports how many were skipped rather than quietly dropping them.
