# Layout Variables Scheme (Base)

Official base layout boilerplate. Spacing tokens reference the Sizes scale; dimension tokens provide useful block widths.

## Recommended usage

- Use `Layout/Spacing/*` for padding, margin, and gap.
- Use `Layout/Dimensions/*` for section widths, container thresholds, and grid widths.
- Keep everything connected to the same `Sizes/...` source of truth.
