• Redesigned dashboard: each module is one clean card that grows to fit its content
• Market Compare and Price History are now separate modules, and they share one product with the Unit Converter
• Rearrange in edit mode: long-press a module title, drag, and a dashed outline shows where it will land. The screen scrolls as you drag to the edges, and you can drop below the last module
