/*
 * Kaval.AI playground widget — shared styling.
 *
 * One stylesheet powers three surfaces, all built from the same console
 * internals (header / API keys / editor / toolbar / output):
 *
 *   1. .kaval-pg-run-btn — the "Run in browser" button injected onto code
 *      blocks in the Sphinx docs.
 *   2. .kaval-pg-panel   — the docs drawer (right-hand panel on desktop, a
 *      bottom sheet on mobile) opened by that button.
 *   3. .kaval-pg-embed   — an inline widget that fills its container; used to
 *      embed the playground on any page and by the standalone
 *      python-playground.html.
 *
 * The console is a self-contained dark "console" so it reads consistently
 * regardless of the host page's light/dark theme.
