契约

• Accessing LazyResult.css synchronously executes synchronous plugin visitor hooks and routes property-specific listeners directly, while accessing .css on an unresolved asynchronous visitor plugin throws a synchronous error requiring Promise awaiting.
• Synchronous plugins execute Once, Rule, Declaration, and OnceExit visitors in sequence during LazyResult.css evaluation.
• Targeted Declaration listeners defined by property name (e.g. Declaration.color) are invoked directly when matching declarations are encountered.
• Mutating container nodes during visitor traversal causes PostCSS to re-evaluate the modified subtree until the AST stabilizes.
• Synchronous access to LazyResult.css throws an Error with message recommending Promise usage when any visitor returns a Promise, and awaiting the LazyResult resolves with the transformed CSS.
