The flat 13-item list read as clutter and reused icons (Team/Meetings,
Work/Sprints, Inbox/Approvals all shared a glyph). Now:
- Primary group leads with the core loop: Home, Work, Team, Messages,
Runs, Files, Approvals.
- A divider demotes the occasional surfaces: Inbox, Documents,
Knowledge, Meetings, Sprints, Social — still one click away, nothing
orphaned (search can't route to several of them).
- Distinct calendar/target/inbox/folder icons end the collisions.
- Every nav glyph is the 18px icon bound in a 24px box; the collapsed
rail centers icons instead of hiding them.
