## Features

### LayoutHandler

`LayoutHandler` is an alternative to `slog.TextHandler`

designed to make output easier to read with:

- Compact output for given attrs by replacing " key=" prefix before value.

- Reorder given attrs by moving them before message (prefix) or after other attrs (suffix).

- Vertical align for prefix attrs by enforcing min/max value width.

- Color output for given attrs.

## Recommendations

### Use NewContextHandler with linter

Disable non-Context slog functions (e.g. `slog.Info`) and methods using linter.

Example golangci-lint v2 config:

```yaml

linters:

  settings:

    sloglint:

      context: all

```
