-- 세션 CSV 내보내기에서 사용자 제공 텍스트가 `=`, `+`, `-`, `@`, 탭·개행 또는 전각 수식 기호로 시작할 때 스프레드시트 수식으로 해석되지 않도록 텍스트 필드 경계를 보강했습니다. 숫자 필드는 기존 숫자 표현을 유지하고, 쉼표·따옴표·개행에 대한 CSV 인용 규칙과 BOM(U+FEFF) 회귀 검증을 함께 유지합니다.
 - 로그인, 회원가입, 비밀번호 재설정이 하나의 공유 비밀번호 계약을 사용하도록 통합했습니다. 입력 처리량을 1,024자로 먼저 제한하고, 현재 `bcryptjs`가 완전하게 검증할 수 있는 72 UTF-8 바이트를 초과하는 값은 조용히 잘라내지 않고 거부합니다. ASCII와 다중 바이트 Unicode 경계 회귀 테스트 및 운영·표준 근거 문서를 함께 추가했습니다.
