Implement UI

Faithful restore of a page-spec. The spec and tokens are the contract; do not "improve" the design while coding.

Process

1. Load contract

• Resolve the page-spec (docs/site/pages/<slug>.md or user argument)
• Read TOKENS.md, DIRECTION.md, BRAND.md
• Read docs/agents/stack.md, docs/agents/design-rules.md
• Skim the existing route/components you will touch

If the spec is missing acceptance checks or hero budget, stop and run/fix /page-spec first.

2. Plan the seam

Name the route and the few components you will add/change. Prefer existing layout primitives. Confirm with the user only if you would create a new pattern that conflicts with the repo.
