Decorate With Parts Task

Problem

A Hanami team needs help with a task in this area:

Use when creating View Parts for decorator-style logic in Hanami 2.x — define Part classes inheriting from Hanami::View::Part, delegate attributes to the wrapped value via delegate :name, :email, to: :value, expose data as a Part in Views with expose :model, as: :model_part, add presentation methods returning formatted strings or booleans (no HTML generation and no database queries in Parts), and access the raw underlying object via the value method when needed.

The team has asked for a concise implementation artifact that a reviewer can inspect without needing to observe the agent's process.

Output

Create answer.md with:

• a short plan for the work
• the concrete Hanami-oriented artifact or recommendation
• the verification steps or quality gates that should be run
• any assumptions that affect the result
