DS Epic: Panel (Bottom Sheet)

### **Description**

The Panel is a container used to display additional details, menus, and prompts without interrupting the current UI context. It utilizes elevation to slide into view over the top of the current screen layout.

Bottom Sheet is a mobile-specific variation of the Panel designed to present important information in a focused and isolated view, temporarily pausing interaction with the rest of the application.

The issue describes a Panel and a mobile Bottom Sheet but names no implementation files, tests, entry points, or acceptance criteria. Clarify the intended scope, supported behavior, and completion criteria before locating the relevant design-system components and tests.
