// Package canvas — variable reference helpers (re-exports).
//
// The canonical VarRefPattern / ExtractRefs / ResolveTemplate
// implementations live in internal/agent/runtime/template.go so
// components can depend on them without importing canvas. This file
// re-exports the symbols for callers that already use canvas.X.
