Vani

Rendering should be explicit, local, and predictable.

Vani is a small, dependency-free UI runtime. It is runtime-first and DOM-anchored, with explicit updates and opt-in fine-grained state.

Core principles

• Explicit updates (no hidden re-rendering)
• Subtree ownership via anchors
• Runtime-first, no compiler
• Opt-in signals for fine-grained updates
• Ref-based and Ref-free DOM subtree access on mount.
