The interaction begins with a tap on the mode selector icon, which slides up a 'Choose a mode' bottom sheet while blurring the background. Tapping the model dropdown within this sheet triggers a fluid container transform (morph) where the bottom sheet dynamically expands in height to reveal the 'Models' selection list. The list items fade and stagger in with a subtle spring. Selecting a model morphs the sheet back down to its original height, updating the selected option. Additionally, toggling 'Incognito mode' dismisses the sheet and morphs the input field style with a sliding toast indicator.
