   HOW TO EDIT THIS FILE:
   - All design tokens (colors, fonts, spacing) live in :root
   - Change accent colors: edit --grad-start and --grad-end
   - Change background: edit --bg-base
   - Change font: edit --font-main (also update the Google Fonts link in index.html)
   - Grid columns: search for .asset-grid and edit grid-template-columns

  like display:flex on .modal-overlay can accidentally override it.
  This rule ensures [hidden] always wins — do not remove it.
