Poem

🐇 I hopped through docs where diagrams lay,
Mermaid lines faded into an image display.
Components listed, flows told with care,
A tidy map now lives right there. 🎨✨

❌ Failed checks (1 inconclusive)

Check name	Status	Explanation	Resolution
Title check	❓ Inconclusive	The title is vague and subjective, using non-descriptive language ('much beautiful') rather than clearly describing the specific changes made to the architecture documentation.	Revise the title to be more specific and objective, such as: 'docs: replace Mermaid diagram with static image and structured architecture table' or 'docs: improve architecture documentation with visual and tabular format'.
