Date Suggestion Injection Plan

Goal

Move date suggestion styling out of apps/www/src/registry/ui/date-node.tsx so the node no longer imports suggestion helpers directly. Suggestion state should be injected from the suggestion plugin layer.

Scope

• Add a test that proves suggestion styling reaches the date trigger through plugin injection.
• Refactor date-node to expose a stable trigger slot only.
• Update suggestion rendering to inject date-specific styling through inject.nodeProps.
• Keep static rendering aligned if the same dependency split is needed there.

Notes

• This is registry work under apps/www/src/registry/; no package changeset expected.
• Relevant prior learning: inline void suggestions need real metadata handling and cannot assume plain text ranges only.

Phases

• Inspect current date, suggestion, and injection paths
• Add regression test for injected date suggestion styling
• Refactor date node and suggestion kit
• Verify build-first checks and lint
• Evaluate compound-worthy learning
