{"content":"[agent-browser-core] Polished standalone modal UI on main. Updated the standalone wallet selector copy to English (`Select a wallet to connect`) and changed the unsupported MetaMask toast to `Coming soon` so the runtime defaults and client fallback copy stay aligned. Replaced text-based modal header close controls with the standard icon close button across the standalone wallet selector, wallet install modal, shared modal template used by the default Document Message flow, and the raw PIN modal. Tightened modal button layout by giving the footer action groups proper spacing. Verified with `npm run build`, targeted standalone/UI modal tests, and full `npm test` (320 passing).","contentType":"text/plain;utf-8","attachments":[],"quotePin":""}
