Upgrade the barn-defense example to use the new high-DPI rendering architecture from the Phaser 2D template, ensuring crisp rendering on retina displays and proper responsive scaling across all screen sizes. Key changes: - Constants.js: Add DPR/PX canvas sizing, scale all spatial values (sizes, speeds, ranges, radii) by PX factor while preserving game logic values (HP, damage, costs, durations) - GameConfig.js: Add Scale.FIT, CENTER_BOTH, zoom: 1/DPR, roundPixels, antialias, preserveDrawingBuffer - index.html: Responsive viewport (max-scale=1, no user-scale), fullscreen game container - main.js: Add render_game_to_text() and advanceTime(ms) test hooks - PixelRenderer.js: Round canvas dimensions for fractional PX scales, use floor/ceil pixel rendering to avoid sub-pixel gaps - All sprites (tiles, enemies, towers, projectiles): Scale by PX - All scenes: PX-scale hardcoded offsets for text, buttons, particles - All UI components: PX-scale button sizes, spacing, fonts, info panels - All systems: PX-scale particle effects, path markers, barn drawing - Grid math preserved: TILE_SIZE = 40*PX, GRID_COLS/ROWS unchanged Co-Authored-By: Claude <noreply@anthropic.com>
