Struct TooltipPlugin 

pub struct TooltipPlugin;

Plugin: registers the four tooltip systems and a default class rule via the LSP completion tables. No render path of its own - the popup is just an <overlay>-shaped entity with a Visuals fill + TextContent, so all standard styling (CSS .tooltip selector, hover-bg, opacity) works.
