/* Browser Popup — floating agent-openable in-app browser window.
 *
 * Paired with ui/browser-popup/js/browser-popup.js (built + shown by the agent's
 * browser_popup tool). Uses design-system tokens only, so it follows the app
 * palette in dark AND light mode. See docs/claude/ui-guidance.md.
 *
 * COLOR SCHEME → all colours are var(--*) from ui/shared/css/design-system.css.
 * REMOVE-WHEN: the Browser Control ability is dropped from the ability catalog.
