- Add comprehensive guidance on tree-shaking and bundle optimization - Document why barrel exports prevent tree-shaking - Provide named import patterns for lucide-react icons - Show dynamic import examples for heavy features - Include import configuration best practices - Demonstrate bundle analysis techniques This update can reduce initial bundle size by 20-40% through proper import strategies and lazy loading of non-critical features.

Why: Performance and bundle size suffer when barrels and wildcard imports prevent tree-shaking and when heavy features are shipped in the initial bundle. This change adds a clear, actionable "Dynamic Import Strategy" to the performance checklist so developers know how to import icons, components, and heavy features to reduce initial bundle size (typical 20–40% reductions).
What: Adds a new section to plugins/spark/skills/spark-app-template/references/performance-checklist.md that:
import * as Icons)Notes for reviewers:
If this should also be added to other templates or repos, say so and I will follow up.
