 * Shared Codepool demo landing-page and explainer styles.
 *
 * The tool and its crawlable guide are one light page, not a dark application
 * followed by a separate white article. Only camera and image viewports stay
 * dark because they are media surfaces. Codepool navigation appears once at
 * the top; the explainer does not repeat it at the tool/article transition.
 *
 * Everything in the explainer markers is Codepool-only. The standalone example
 * keeps its original application theme when sync_demo_example.py strips this
 * stylesheet and the guide.
