M2 style packages and evaluation ownership

Objective

Establish distinct chart style packages, adopt and improve the existing evaluation tooling for chart work, and turn early design exploration into reusable chart-library assertions.

Deliverables

• [ ] Lock at least two distinct style packages that differ in both structure and theme.
• [ ] Take ownership of the existing chart-evaluation tooling for chart-library review and regression detection.
• [ ] Produce an initial design-assertions corpus from chart exploration.

Tasks

• Dual style packages — not_started
• Chart evaluation ownership and improvement — not_started
• Design assertions foundation — not_started
