/* CloseFlow asset picker (Wave 4, W4-11). Controller: static/js/asset-picker.js.
   Modal chrome comes from ds-modal.css; this file styles the picker tabs, search,
   and grid. Card dialect copied from the Assets library surface (assets.html
   .ax-card family), namespaced .cfap- so the mockup-locked page never drifts.
   Tokens only (tokens.css); app is light-only. */
