🎨 Palette: Enhanced documentation architecture and accessibility

[Igor Holt (igor-holt)]

💡 What:

• Enhanced the Mermaid architecture diagram with semantic node shapes (([Stadium]) for workloads, {{Hexagon}} for specialized scheduling) and dashed layer borders.
• Added "AI Workloads" and "aSHARD VRAM Pinning" to the architecture diagram to better reflect the project's scope.
• Added descriptive title attributes to key external links (Igor Holt, Genesis Conductor Engine) and the license link.

🎯 Why:

• The previous diagram was missing components described in the text, creating a cognitive gap for users.
• Distinct node shapes help users quickly categorize components (Workloads vs. Infrastructure vs. Core).
• Link titles improve accessibility for screen readers and provide helpful tooltips for mouse users.

♿ Accessibility:

• Improved screen reader support for links via title attributes.
• Added a title to the Mermaid diagram for better context.

Code Review

This pull request updates the documentation by adding a new UX/accessibility learning entry to .Jules/palette.md and applying it to README.md by adding descriptive title attributes to external links. Additionally, the architecture Mermaid diagram in README.md has been enhanced with a title, new nodes, updated connections, and styled subgraph borders. Feedback was provided to use comma-separated values for the stroke-dasharray style properties in the Mermaid diagram to prevent potential rendering issues.

Important

The consumer version of Gemini Code Assist on GitHub is being sunset. Starting June 18, 2026, new organization installations will be blocked, and all code review activity will officially cease on July 17, 2026.

In Mermaid style definitions, using space-separated values for properties like stroke-dasharray (e.g., 5 5) can cause parsing errors or rendering issues in some Markdown/Mermaid renderers. Using a comma-separated value (e.g., 5,5) or a single value (e.g., 5) is more robust and widely compatible.
