Description

When focusing a series by hovering, the focus.alpha setting allows you to de-emphasize all other series by adding transparency to them. I find that effect a bit too visually jarring and would like to achieve the opposite, where only the series that is currently focused gets emphasized somehow, while all others keep their style. Ideally the emphasis wouldn't be alpha-based (since alpha is already 1), but would allow me to change the color or width of the series.

Research direction

Start by reading the hover focus behavior and the existing focus.alpha setting described in the issue. Trace how the focused and non-focused series styles are applied, then determine the smallest API change that supports focused-series color or width changes without altering other series. Done means the behavior is configurable and covered by an example or test demonstrating unchanged styles for non-focused series.
