// 设计说明：
|

// 1) 本 schema 使用 sqlite provider（本地 MVP / 离线开发）。
|
||||
// 字段全部使用 String / Int / Float / Boolean / DateTime 等跨库通用类型，
|
||||
// 不使用 Prisma enum 与 @db.* 原生类型，因此可平移到 MySQL。
|
||||
// MySQL 版本见同目录 schema.mysql.prisma，切换步骤见 docs/mysql.md。
|
||||
// 2) 角色与优先级用 String 存储（'ADMIN' | 'TEACHER' | 'STUDENT'、
|
||||
// 'LOW' | 'NORMAL' | 'HIGH' | 'URGENT'），在 API 层用 zod 校验，
|
||||
// 这样 SQLite / MySQL 行为完全一致。
|
||||
// 3) 所有主键使用 cuid 字符串，便于多端离线生成与合并。
