Repository instructions

• Read README.md before making changes and keep its change history and planned cleanup list current.
• Prefer simple Markdown-based editing workflows; the website owner does not normally work with HTML or Jekyll internals.
• Preserve the existing design and make small, scoped changes unless a broader redesign is explicitly requested.
• Treat this repository as public. Never add secrets, access tokens, private notes, or sensitive personal information to tracked files, and check changes for such information before committing or pushing.
• Validate relevant configuration and content after editing.
• Do not commit or push changes unless the user explicitly requests it.
