Style Guide (ASCII only)

Rules: - ASCII characters only. Avoid smart quotes, long dashes, and special bullets. - Use "-" for bullets and "--" only in code blocks. - Use "->" instead of arrows. - Use simple headings: "#", "##", "###". - Keep lines under 120 chars when practical. - Diagrams: prefer Mermaid in markdown code fences.

Example Mermaid: ```mermaid flowchart LR A[Start] --> B[Do work] --> C[Finish]
