/* EmojiPicker (Elevate.Client/Shared/Components/Common/Emoji/EmojiPicker.razor).
   Global file on purpose: Client .razor.css never loads (see .claude/chapters/blazor-rendering.md).
   Every colour comes from MudBlazor palette tokens so the picker follows dark mode.
   --elevate-kb-inset / --elevate-vv-height are set on <html> by emojipicker.js while a picker is open
