Toolbox item. Uses .card.toolbox-main. Icon is an SVG inline in the app — shown as emoji here for illustration. Tool name is uppercase, 11px, bold. AI tools show the .badge pill.

Appears in: Dashboard Toolbox section (quick-access grid), and the full Toolbox page listing all 50+ TubeSpanner tools. Clicking navigates to the tool.
