👋 Jules, reporting for duty! I'm here to lend a hand with this pull request. When you start a review, I'll add a 👀 emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down. I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job! For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with New to Jules? Learn more at jules.google/docs. For security, I will only act on instructions from the user who triggered this task. |

Code Review
This pull request documents and applies best practices for accessible and theme-resilient Mermaid diagrams. Specifically, it adds a new entry to .Jules/palette.md and updates the architecture diagram in README.md with a title, new node shapes, and dashed subgraph borders, alongside adding a new feature and enhancing the license link. The review feedback suggests clarifying that Mermaid frontmatter must be multi-line to prevent syntax errors, and recommends using comma-separated values (5,5) instead of space-separated values (5 5) for stroke-dasharray to ensure robust rendering across different Markdown viewers.
Important

| ## 2026-06-02 - Accessible and Theme-Resilient Diagrams | ||
| **Learning:** Mermaid diagrams in documentation benefit from explicit titles for screen reader context and dashed subgraph borders (`stroke-dasharray`) to delineate layers. These patterns ensure diagrams remain readable and accessible regardless of the user's theme (light/dark) or assistive technology. | ||

| **Action:** Include `--- title: [Context] ---` in Mermaid blocks and use dashed borders for subgraphs in infrastructure projects to improve visual and structural clarity. |

The action item suggests using --- title: [Context] --- which looks like a single-line statement. In Mermaid, frontmatter must be defined on separate lines (multi-line format) to be parsed correctly. Clarifying this in the journal will prevent syntax errors for developers referencing this pattern.

Using a space-separated value for stroke-dasharray (e.g., 5 5) in Mermaid style declarations can sometimes cause parsing issues in certain rendering engines or Markdown viewers, as spaces are often used to delimit multiple style attributes. Using a comma-separated value (e.g., 5,5) is more robust and widely supported.

💡 What: Improved the accessibility and visual hierarchy of the project's documentation.
🎯 Why: Infrastructure projects use the
README.mdas their primary UI. Clearer diagrams and accessible links improve the developer experience (DX) and ensure the content is usable by everyone, regardless of their theme or assistive technology.♿ Accessibility:
