- Service: accounts with Argon2 password hashes and session tokens; the first login creates the admin (shared savegames of before move to the admin); the admin creates and deletes users; everybody can change the password; savegames are stored and listed per user - Game: login page before the title (only when the service is reachable), with licence and repository link; account page (password, logout; users for the admin); text fields with Tab/Enter, masked passwords, browser dialog on touch screens; long status messages wrap - Download Standalone: DungeonCraft.html with the game embedded (built in the Docker image, served to logged-in users via nginx auth_request); works from file:// without server and opens downloaded savegames - Without the service (standalone, local files) there is no login, savegame files as before Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

"""Builds DungeonCraft as one self-contained HTML file (no server needed, works from file://).
|
|
|
|
The JavaScript bundle, the plugin and the WASM module (base64) are embedded; fetching
|
|
"dungeoncraft.wasm" is answered from the embedded bytes. Service worker and manifest are left
|
|
out. Without the savegame service the game uses savegame files (download / file picker), so
|
|
savegames downloaded from the server open in the standalone version as well.

usage: make_standalone.py <www dir with dungeoncraft.wasm and mq_js_bundle.js> <output.html>
