What to build

Reduce frontend bundle cost and establish an enforceable guardrail so future changes do not silently bloat the application. This slice should target the biggest current bundle contributors, improve chunking, and define a lightweight build-size check that maintainers can rely on.

Acceptance criteria

• The build no longer emits the current chunk-size warning for the targeted oversized path, or the remaining exception is explicitly justified.
• At least one meaningful code-splitting or lazy-loading improvement lands for a high-cost frontend path.
• The project gains a simple repeatable way to track build-size regressions.
• Verification records bundle-size before/after for the targeted chunk(s).
