   Alliant Games — EspoCRM 10.0.3  |  Knowledge Base card browser
   Install path on server: client/custom/css/knowledge-base-cards.css
   Loaded via: custom/Espo/Custom/Resources/metadata/app/client.json

   THEME-SAFE: cards, badges, search box, toggle, article list and article pane
   reuse EspoCRM's own `.panel`, `.label`, `.btn`, `.list-group`, `.form-control`,
   `.complex-text` and `.text-*` classes, so they follow the active theme. This
   file only adds LAYOUT (grid, fixed card sizes, hover) plus a couple of brand
   accent colors (the article icon, the hover bar). Switch themes and the themed
   parts recolor themselves.

   Scoped under `.kb-cards` so it can't leak elsewhere.

   Brand accent (edit to match the login screen palette):
     --ag-blue: #2563EB   --ag-purple: #7C3AED   --ag-cyan: #22D3EE
