Use the canvas-design Skill.

Create a finished 1200 × 1600 brand poster for HarborMug using restrained blue, harbor rhythm and minimal English labels. Develop a coherent visual direction, use original geometry and typography instead of an invented product photograph, refine the composition and export a PNG plus a print-friendly PDF.

The attached business materials are:
- inputs/merchant.json
- inputs/request.json

Deliver a complete result.md report that the operations team can read, plus any finished files needed for this task. Keep supporting calculations and evidence with the deliverables. Write the report in English; use the requested target language for customer-facing copy. The business datasets are fictional examples unless the brief explicitly names a live public website.
