## Why this rule exists

Some providers cap the website field at 100 characters and truncate silently rather than erroring, which produces a stored URL that no longer resolves. A deep link with tracking parameters overruns easily.

## How to fix it

Use the bare site root without tracking parameters or deep paths in the brand website field.
