V405 — LOAD EXISTING FULL-PARTY SAVE GAMES
===========================================
Base: V404; no changes to character Import/Export, account login, autosave,
character folder, character ownership prefixes or the no-respawn guards.

WHY THE LOAD BUTTON WAS GRAY
The BG2 native LOAD screen showed existing saves such as:
  Debut du Chapitre 10, Sauvegarde-Finale-ToB, Chapter 8 Start,
  Sauvegarde-Auto-ToB.
V404 required an account-specific DRKxx_account_campaign_ prefix even for
manual loading. Existing BG2 save names without that prefix were visible but
could not be selected for loading.

WHAT CHANGED
* In the native Load screen, select the existing save, then click Charger
  (Load) or double-click the selected row. Both routes now use one guard.
* Logged-in host accounts may manually load unprefixed native BG2 saves,
  including full-party saves. No conversion of .SAV files is attempted.
* Saves explicitly named DRKxx_<account>_... can be loaded only by that account.
  Manual loading is permitted across that account's campaign codes.
* Resume Campaign still auto-picks only saves identified as belonging to
  the authenticated account. Old unprefixed saves require manual selection;
  Resume does NOT auto-pick ambiguous unprefixed saves.
* Save Game, autosaves and imported/exported .CHR files remain untouched.
* This cannot establish the original owner of an unprefixed save. Legacy
  saves are accessible to authenticated host accounts sharing this BG2
  save profile. Rename/re-save using a new account-tagged slot if separation
  is required going forward.

RECOMMENDED INSTALLATION AFTER V404
1. Close BaldurII.exe.
2. Extract the V405 ZIP.
3. Run APPLY_V405_NATIVE_PARTY_LOAD_UI_ONLY.bat and select the BG2 install
   folder containing BaldurII.exe (NOT Documents/BaldursGate2Online).
4. Open BG2, log in and select the desired saved game, then click Charger.
Only override/UI.MENU is rewritten; no .SAV, profile, password or CHR files
are opened, removed, moved, overwritten or copied by this update script.

FULL INSTALL
SETUP_IN_GAME_ACCOUNTS.bat includes the V405 change. Full setup may modify
account router/configuration files, so the UI-only patch is safer for V404.

CHECKS
* Script-level tests of the BG2 native Load handler, legacy save allowance,
  account-tagged save isolation, and double-click path.
* Lua chunk syntax and menu structural checks.
* UI-only installation tested on read-only UI.MENU and for repeat application.
* Actual BG2/Windows gameplay loading has not yet been verified.
