• Homepage announcement retarget — The homepage AnnouncementBadge text changes to ArkEnv v1 is in alpha! and its href points to the external v1 alpha docs at https://arkenv-v1.vercel.app/, matching the README callout. Verified the target is live, isExternalUrl correctly drives the <ArrowUpRight> external-link icon, and no tests or internal references depend on the removed "Presets" badge.

✅ No new issues found.

Reviewed changes — Reviewed the incremental delta of PR #1738 since the prior Pullfrog review at 352cd8f7 (1 new file, 1 new commit).

• New-tab fix for external announcement badge — AnnouncementBadge (apps/www/components/announcement-badge.tsx) now computes isExternal = isExternalUrl(href) once and sets target="_blank" + rel="noopener noreferrer" for external hrefs, while internal links (relative paths, arkenv.js.org, localhost) keep default same-tab behavior. This directly resolves the prior review's external-link UX rough edge, and the new-tab behavior now matches the auto-detected <ArrowUpRight> icon. isExternalUrl correctly classifies https://arkenv-v1.vercel.app/ as external; no other AnnouncementBadge usages exist, so the behavior change is fully contained.
