Module animation 

Pure animation evaluation and hierarchical type-erased composition.

The runtime tree is a closed world of node content (NodeContent): the time-combinator vocabulary (sequence, stack) plus the leaf forms. This module is split by layer:

• node — the closed runtime core and all structural interpreters;
• eval — the open, typed visual-leaf protocol;
• build — the lowering protocol from authoring definitions to AnimNode;
• compose — authoring sugar (AnimSequence, AnimStack, AnimLagged) that lowers to the core vocabulary.

Authoring is open above the core: user leaves enter through Eval, and combinators expressible as placements (e.g. AnimLagged) desugar into the primitives in IntoAnimNode.
