Coverage for src/lilbee/cli/tui/screens/command_palette.py: 100%

1"""Textual's command palette with the search icon replaced. 

2 

3Textual seeds ``SearchIcon`` with a magnifying-glass emoji, which the system 

4emoji font renders in its own colors at double width, making it the one element 

5on screen that ignores the theme. 

6 

7``SearchIcon`` is built inside ``CommandPalette.compose`` and ``icon`` is a 

8reactive, so the icon is set after mount rather than by overriding ``compose``, 

9which would mean copying the library's layout. The query is deliberately not 

10``query_one``: if a future Textual restructures the palette, the icon reverts 

11rather than raising out of the Ctrl+P action.
