/* pickers.css: emoji picker, GIF picker and the combined tabbed picker
   Flattened from the Blazor scoped CSS at commit 7af3454 (parent of 2c1b6c0 "Step 1: remove Blazor").
   Selectors and declarations are copied as they were; only ::deep was removed and a root
   class was put in front of selectors whose class names collided between components.
   See README.md in this folder for the prefixes and the dropped rules. */
