/* pmg-compare.css (cmp-1, 2026-05-23)
 *
 * Spec 2 — Multi-Model Compare. Modal launched from #result-top-compare
 * showing the same prompt as ChatGPT/Claude/Gemini-style responses side
 * by side. z-index matches pmg-template-browser (100050) so only one of
 * the two top-level modals can be visible at a time.
 *
 * All colors via --color-* tokens.
