Module stylesheet 

CSS-like model/provider stylesheet parser and applicator.

Selectors:

• * (specificity 0) — matches all nodes
• .class (specificity 1) — matches nodes with that class
• #node_id (specificity 2) — matches a specific node

Later rules of equal specificity win. Explicit node attributes always override stylesheet values.
