# Quick Chat elevation

## Why

Quick Chat opens over the current page with a transparent backdrop, so the floating panel can
blend into the page and its opened state is not immediately clear. Users need a restrained visual
separation that makes the panel feel elevated while preserving the surrounding page as context.

## What

- When Quick Chat opens at tablet or desktop widths, the page behind it is visually de-emphasized by
  a subtle semitransparent backdrop.
- The Quick Chat panel remains above the backdrop with its existing elevation shadow, dimensions,
  position, content, and interaction behavior unchanged.
- Closing Quick Chat removes the backdrop and restores the page's normal appearance and interaction.
- On phone widths, Quick Chat keeps its existing full-screen composition, explicit close control,
  and viewport containment. The backdrop does not need to be visible because the panel covers the
  viewport.

## Scenarios

- **GIVEN** Quick Chat is closed on a tablet or desktop viewport, **WHEN** the user opens Quick Chat,
  **THEN** the Quick Chat dialog is visible above a non-transparent backdrop and its computed panel
  shadow is not `none`.
- **GIVEN** Quick Chat is open on a tablet or desktop viewport, **WHEN** the user closes it,
  **THEN** the dialog and backdrop are removed so the page is fully visible again.
- **GIVEN** a phone viewport, **WHEN** the user opens Quick Chat from an existing mobile entry
  point, **THEN** the full-screen dialog remains usable, the explicit close control remains
  reachable, and the document has no horizontal overflow.

## Out of scope

- Changing Quick Chat size, position, responsive composition, content, sessions, or persistence.
- Adding a new backdrop component, user setting, animation, or navigation behavior.
- Changing the separate new-Quick-Chat picker dialog or configuration-chat popover.
