+Use the user identity from `git config user.name` to filter all per-repo git data.

+**Rules for the personal card:**
+- Only show repos where the user has commits. Skip repos with 0 commits.
+- Sort repos by user's commit count descending.
+- For LOC, use "k" formatting for thousands (e.g., "+64.0k" not "+64010").
+- Role: "solo" if user is the only contributor, "team" if others contributed.
+- Ship of the Week: the user's single highest-LOC PR across ALL repos.
+- Top Work: 3 bullet points summarizing the user's major themes, inferred from
+  commit messages. Not individual commits — synthesize into themes.
+  E.g., "Built /retro global — cross-project retrospective with AI session discovery"
+  not "feat: gstack-global-discover" + "feat: /retro global template".
+- The card must be self-contained. Someone seeing ONLY this block should understand
+  the user's week without any surrounding context.
+- Do NOT include team members, project totals, or context switching data here.
+
+**Personal streak:** Use the user's own commits across all repos (filtered by
+`--author`) to compute a personal streak, separate from the team streak.
