**Error** from the build tools, while Vite builds or serves your app.

## What happened

This line is a summary. The build found errors in one `.tsrx` file and stopped.

The error message reads:

```text
MARKLESS_COMPILE_BLOCKED: <filename> has <length> compiler error(s).
```

Words in angle brackets change from case to case.

## How to fix it

## Where it comes from
