Highlights

- Lab flow was adjusted so the lab menu controls enemy spawning more explicitly, and the default training enemy was removed from the lab room.
- Character selection received a major presentation pass: a terminal-inspired layout, cleaner passive cards, revised keycap drawing, updated room setup, selectable character thumbnails, and player tint placeholders.
- Map navigation was rebuilt into a branching tree with terminal-style panels, room icons/sprites, selected-room highlighting, and tighter integration with roll-chance information.
- The broader UI was unified around a shared SU-93 terminal style, including HUD, menu, market, result, history, special, game-over, win, settings, tutorial, compendium, and lab screens.
- Roll chance progression was rebalanced with a 20% cost increase and improved display behavior during the roll animation.

Lab menu and enemy spawning

- Updated the lab UI creation and drawing flow to better support menu-driven lab setup.
- Added lab step logic to manage enemy spawning from the menu state.
- Reworked lab presentation so setup choices are clearer before entering combat tests.

Removed default lab training enemy

- Removed the pre-placed/default training enemy from the lab room.
- Simplified lab UI creation now that enemy spawning is controlled by the lab menu flow.
