Living record of the design decisions that shape this project. These mirror the per-project Claude memory but are version-controlled so they travel with the repo.
- overview.md — goals, hard constraints, non-goals, SVG-as-truth commitment.
- stack.md — chosen Rust crates and workspace layout.
- features.md — scoped features and the two distinctive differentiators (rulers-as-entities, parametric design system).
- status.md — current phase, task list, next steps. Update after each working session.
Dates on decisions are absolute so they remain interpretable over time.
