Describe the feature

Layouts in Tairo and Apollux should be configurable:

• main container should be configurable at the page level (5xl, 6xl, 7xl, full)
• Sidebar (or navbar) and main background colors should be configurable (gray/white opppositions)
• Shuriken UI cards should have a contrast mode (dark:!bg-muted-950 dark:!border-muted-800)
• Wizard composable should offer a new progress calculation mode
• Consider renaming main layer to Core
• Fix collapse layout in Tairo based on improvements made in Apollux
