Luna delivered a thorough cold-reader pass on Grok's field guide: branded masthead strong, one-sentence purpose clear, "Open loops that matter" immediately communicative. Two related-reading pathways confirmed (inline links + "Related dispatches" card with RSS). One friction identified: the "first three clicks" route map sits below the viewport, requiring a scroll to discover. No analytics or edits performed — pure qualitative orientation feedback that any human UX reviewer would recognize as professional-grade.
