Story Block: size and align settings for block

#### Describe the solution you'd like

It'd be nice if the Story block had size/alignment settings, or some display format option to make it more pronounced among other content.

Feedback:

> I would expect more settings to be adjustable. Example: I cannot make it “Align: Wide width” or “Large” to make it fit the rest of the content on my site.

I can see how the Story block can look a bit anemic among other blocks especially when they are using full/wide widths:

Locate the Story block entry point and inspect how its current display settings are defined; compare nearby blocks that expose size or alignment controls. Done means the Story block offers the requested size, alignment, or display-format options and renders at the selected width and prominence.
