- Replaced experimental badge with a high-visibility GitHub Alert.
- Improved accessibility of the License badge with more descriptive alt-text.
- Added a Mermaid architecture diagram to visualize the orchestration layers.
- Styled the Arbiter Core node for better visual hierarchy and focus.
- Updated the Palette journal with learnings on visual hierarchy in diagrams.

 **Learning:** For infrastructure or backend projects without a functional frontend, the `README.md` serves as the primary User Experience (DX/UX). In these cases, micro-UX improvements shift from ARIA labels to scannability, clarity of project status, and informative (non-redundant) feature lists.
 
 **Action:** Treat the `README.md` as the landing page. Use visual status indicators (badges), scannable bullet points with representative emojis, and ensure that headers provide a clear path for the user to understand the project's utility and maturity.

+## 2026-05-20 - Visual Hierarchy in Architecture Diagrams
+**Learning:** In complex orchestration diagrams, the primary component (e.g., 'Arbiter Core') can get lost among infrastructure and cloud-native layers. Using specific Mermaid styles (fill color, stroke width) and unique node shapes (double-circle) establishes a clear visual focal point.
+
+**Action:** For the primary orchestration node in Mermaid diagrams, use double-circle syntax `((Node))` and apply styles `fill:#f96,stroke-width:4px` to distinguish it from secondary components.

 `arbiter` is a specialized orchestration layer designed for high-performance computing environments. It bridges the gap between low-level hardware management and cloud-native scheduling, providing a unified interface for managing virtualized resources with precision.
