Control

Remarks

Three things, and deliberately not more. Whether it is disabled, how prominent it is, and how big — because those are the three questions asked of every control by somebody who is not writing a stylesheet. Everything else a control looks like is CSS, which is the whole reason the styling engine exists.

⚠ ControlVariant and ControlSize are written through to classes — variant-primary, size-sm — rather than read by anything here. That is what puts them in reach of the cascade: a game can restyle button.variant-danger, add a variant of its own with a plain class, and override one control's size with a selector, none of which is possible for a property this assembly interprets itself.

The class names are prefixed because they land in the same namespace as the application's own. .primary would be a collision waiting to happen in every project that has ever had a primary anything.
