V122 PHYSICAL LOCAL ACCOUNT CHARACTER FOLDERS

- CREATE ACCOUNT / LOG IN stays inside BG2.
- No account/network server is used.
- SAVE ACCOUNT CHARACTER and LOAD ACCOUNT CHARACTER become available immediately after a valid login; they do not wait for a router confirmation.
- BG2 only reads/writes the directory named "characters". While an account is logged in, that account's physical folder is temporarily named "characters".
- On LOG OUT or account switch, that same folder is renamed on the same drive to characters_<full account name>.
  Examples:
    Drakhysys -> characters_drakhysys
    Rulehyr   -> characters_rulehyr
    Yllia     -> characters_yllia
    Yllidia   -> characters_yllidia
- Full account names avoid first-four-character collisions.
- No character is copied, backed up, restored, merged, duplicated, or automatically respawned.
- Existing loose non-account characters are renamed once to characters_unassigned rather than assigned to a new account.
