Pinned at 4258ee44. Observatory web only, no schema change, deployed web-only.
- Sidebar groups are readable and evenly spaced, with a divider between groups.
- A theme button in the header, next to the account controls.
- A compact account chip that shows one short line and the organization name without its code.
- Sign out is plain text rather than a menu item.
- The posture meter is bound to the score instead of to a fixed value.
Rollback target was the previous web image; the server, control plane and Constellation images were unchanged.
