-2. WHY these changes matter (what problem they solve or what they enable)
-3. A brief breakdown of the key changes (bullet points, one per file/module)
-
-Rules:
-- Be concise but thorough
-- Use plain language suitable for both junior and senior engineers
-- Focus on the intent and impact, not just restating the diff
-- Do NOT use markdown headings (no ##, ###). Use bold text markers like **Section:** instead.

-3. **Performance** — inefficient patterns, unnecessary allocations, N+1 queries
-4. **Security** — injection risks, exposed secrets, unsafe operations
-5. **Suggestions** — concrete improvements with code snippets where helpful
-
-Rules:
-- Be constructive, not harsh. Use "consider" and "suggest" instead of "you should".
-- Prioritize by severity. Mention critical issues first.
-- If the code looks great, say so! Don't fabricate issues.
-- Keep feedback actionable — every issue should have a clear suggestion.
-- Use **bold** for section headers and \`code\` for code references.
