Generate a short, imperative commit message for the current changes. Output only the message; do not run git commit unless asked.

1. Review changes: git status and git diff (or git diff --cached if staged)
2. Write a single-line message under 72 characters
3. Use imperative mood: "add", "fix", "update" — not "added", "fixed", "updated"
4. Start with a verb, no period at the end
5. Output only the message text (e.g. add login and signup buttons to home page)

Prefer conventional commits when it helps clarity:

• type(scope): description — e.g. fix(auth): handle expired session
• Or plain imperative: add dashboard logout form

• Concise: One line, ideally under 50 characters
• Imperative: "fix bug" not "fixed bug"
• Specific: Describe what changed, not vague labels
• No period at the end
