V320 - FIVE LETTER ACCOUNT CHARACTER PREFIXES ONLY

Built from the untouched V319 ZIP. V319 native Import/Export panels remain.

Drakhysys -> drakh01.CHR, drakh02.CHR
Kronas -> krona01.CHR, krona02.CHR
Drakkar -> drakk01.CHR

Five-character prefixes are assigned per logged-in account; duplicates are
automatically assigned distinct five-character aliases and recorded in
_DRAKHYSYS_NATIVE_CHR_PREFIXES_V320.json in the BG2 profile.

Only numbered five-character alias files are allowed in the verified native
Import list. Character source files must also begin with the five-character
prefix and reside inside the authenticated account's folder.

The V319 three-letter alias registry and physical CHR/BIO files are left
untouched; three-letter aliases are intentionally NOT used by V320. As a
result old filenames like dra01.CHR and kro01.CHR are not visible in V320
Import unless separately re-exported under a qualifying five-letter name.
No automatic migration, backup, rename, move, or deletion occurs.

Run SETUP_IN_GAME_ACCOUNTS.bat with BG2 closed and launch InfinityLoader.exe.
Preserve your V319 ZIP as the rollback.
