Struct StyleRule 

pub struct StyleRule {
    pub select: String,
    pub interaction: Option<Interaction>,
}

A CSS-like style rule: a selector + the properties it attaches to matching placements. Lets a world define behaviour by type / .class / #id once, instead of inline on every placement — restyle everything from one rule.

"styles": [
  { "select": ".harvestable", "interaction": { "label": "Chop", "effects": ["despawn"] } }
]

Fields

select: String

A simple selector: "tree" (type), ".harvestable" (class), "#hero" (id).

interaction: Option<Interaction>

The declarative interaction this rule attaches. (More properties — mesh, material — cascade here as the layer grows.)
