sudoevolve/EvolveUI ? reverse-engineered prompt

Build me a polished Qt 6 QML component library called EvolveUI that looks and feels modern, clean, and consistent across desktop and mobile. I want a set of reusable UI pieces like buttons, cards, inputs, dialogs, drawers, menus, tabs, charts, tables, sliders, switches, and a few demo pages that show them off in a nice layout. Make the whole thing support light and dark themes from one shared theme file, with smooth animations, soft shadows, rounded corners, and responsive sizing so it adapts well when the window changes.

Please also include a simple starter app that opens with a nice main screen and showcases the components in action, plus a small scaffold or template so I can reuse the library in a new project easily. If anything needs current Qt or QML guidance, look up the latest docs online. Keep the styling elegant and inspired by modern mobile and desktop design, with a strong focus on polish and usability.
