/review

Review the code I've selected or the recent changes for:

• Bugs & edge cases — off-by-one errors, null dereferences, unhandled exceptions
• Security concerns — injection vectors, exposed secrets, unsafe deserialization
• Performance issues — unnecessary re-renders, N+1 queries, memory leaks
• Readability improvements — naming clarity, function complexity, dead code

Be concise and actionable. Group findings by severity (critical, warning, suggestion). Skip praise — only flag real issues.
