Build me a React component library that gives apps a classic Mac OS 8 style desktop and windowed interface.

I want the main package to export reusable components like a desktop shell, menu bar, app windows, dialogs, buttons, inputs, tabs, tables, sliders, checkboxes, dropdowns, and tooltips, all with that retro Platinum look. It should also include things like a boot screen, about window, app switcher, sound support, screen savers, and a simple theme system so I can customize colors and typography from JSON. Make sure the components work nicely together inside a desktop style app, with window controls like close, zoom, collapse, resize, and modal dialogs.

Please also include an example app or demo page I can run locally to see everything working, and make the styling feel authentic rather than just themed modern UI. If anything is unclear, check the docs or look up current references online before filling in the details.
