+/**
+ * Builds the full "Last seen ..." sentence shown on profiles and similar UI.
+ *
+ * Unlike [timeAgo], which can return a bare absolute date string (e.g. "Jan 14")
+ * for older timestamps, this function always returns a self-contained, grammatical
+ * description such as:
+ *
+ *   - "Last seen 5 minutes ago"
+ *   - "Last seen 2 hours ago"
+ *   - "Last seen 3 days ago"
+ *   - "Last seen 2 weeks ago"
+ *   - "Last seen on Jul 27, 2024 (9 months ago)"
+ *   - "Last seen on Jan 14, 2024 (1 year ago)"
+ *
+ * The duration component uses sensible units (seconds/minutes/hours/days/weeks/months/years)
+ * and pluralizes via Android plural resources. For anything older than a week we also
+ * include the absolute date so users see exactly when the activity happened.
