+           Checking `src/app/api/auth/register/route.ts` would be ideal, but I don't have it open.
+           In `src/app/api/account/export/route.ts`, I implemented encryption using:
+           encryptPrivateKey(privateKey, password) returning { encrypted, salt, iv }
+           
+           BUT the database schema `users` table has:

+           I need to know how it's stored in the DB. Is it a JSON string?
+           Or perhaps `privateKeyEncrypted` is JUST the base64 string and salt/iv are stored elsewhere?
+           
+           Let's check `src/app/api/auth/register/route.ts` OR how I used it in export.
+           In export route I WROTE `encryptPrivateKey` myself.
+           
+           Let's look at `src/db/schema.ts` lines 36-37:
+           privateKeyEncrypted: text('private_key_encrypted'), 
+           
+           If I look at `import` route:
+           It takes the exported JSON (which has separated fields) and creates the user.
+           const [newUser] = await db.insert(users).values({ ... privateKeyEncrypted: privateKey ... })
+           Wait, in import route I decrypt it using the password, then I insert it...
+           WAIT. The import route inserts `privateKeyEncrypted: privateKey`. 
+           This implies `privateKeyEncrypted` column implies it SHOULD be encrypted, but if I'm inserting the RAW private key there... that's bad.
+           
+           Let's verify `src/app/api/account/import/route.ts`.
