``` **Changes Made:** 1. **HTML Structure:** Added divs `#title-screen` and `#class-selection-screen`. Added a general `.hidden` class to manage visibility. The main game content is now wrapped in `#game-container`. 2. **CSS:** Added styles for the new screens, including centering content, button styling, and descriptions. Added the `.hidden` class (`display: none !important;`). 3. **JavaScript - Game States:** * Introduced `gameState` variable (`'title'`, `'classSelect'`, `'playing'`, `'gameOver'`). * `initGame` now starts in the `'title'` state. * `setupScreens` function manages which container (`#title-screen`, `#class-selection-screen`, `#game-container`) is visible based on `gameState`. 4. **JavaScript - Class Selection Flow:** * `setupTitleScreenListeners` waits for the start button click. * Clicking start changes `gameState` to `'classSelect'`, shows the class screen, and sets up `setupClassSelectionListeners`. * `classes` object defines starting stats and passive names for each class. * `selectClass` function is called when a class button is clicked. It copies the chosen class's stats to `player.stats`, stores the class name and passive name, and then calls `startGame`. * `startGame` function transitions `gameState` to `'playing'`, sets up the actual game environment (generates floor, updates UI, starts loop, sets up keyboard input), and shows the `#game-container`. 5. **Passive Abilities:** Defined `passiveName` in the `classes` object. The `startGame` function logs the chosen class and passive name. The actual *effects* of the passives are not implemented in this version. 6. **Initialization Timing:** Player stats are now set *during* `selectClass`, so `updateStatsDisplay` is called *after* stats are initialized in `startGame`. Player placement in `generateFloor` also happens *after* class selection. Click "Preview" to see the new title and class selection screens before the main game starts, Col
