The Dockerfile uses `nginx:alpine` with NO custom nginx config — the default config may not serve JS module files with correct MIME types, and lacks proper `try_files` handling\n2. Vite builds with absolute paths (`/assets/...`) which break if there's any path mismatch in the serving layer\n3. No `.dockerignore` exists, potentially causing build context issues\n\n## What to Fix\n\n### 1. Create `nginx.conf` (new file)\n\nCreate a minimal nginx configuration that properly serves a static SPA:\n\n```nginx\nserver {\n listen 80;\n server_name _;\n root /usr/share/nginx/html;\n index index.html;\n\n location / {\n try_files $uri $uri/ /index.html;\n }\n\n location /assets/ {\n expires 1y;\n add_header Cache-Control \"public, immutable\";\n }\n\n gzip on;\n gzip_types text/plain text/css application/javascript application/json image/svg+xml;\n gzip_min_length 1000;\n}\n```\n\n### 2. Update `Dockerfile`\n\nReplace the nginx stage to use the custom config:\n\n```dockerfile\nFROM node:22-alpine AS build\nWORKDIR /app\nCOPY package*.json ./\nRUN npm ci\nCOPY . .\nRUN npm run build\n\nFROM nginx:alpine\nCOPY nginx.conf /etc/nginx/conf.d/default.conf\nCOPY --from=build /app/dist /usr/share/nginx/html\nEXPOSE 80\n```\n\nKey change: `COPY nginx.conf /etc/nginx/conf.d/default.conf` — this replaces the default server block with our custom one that properly handles static file serving.\n\n### 3. Update `vite.config.ts`\n\nAdd `base: './'` so built assets use relative paths instead of absolute:\n\n```typescript\nimport { defineConfig } from 'vite';\n\nexport default defineConfig({\n base: './',\n build: {\n target: 'ES2022',\n },\n});\n```\n\n### 4. Create `.dockerignore` (new file)\n\n```\nnode_modules\ndist\n.git\n.github\n*.md\n```\n\n### 5. Update `index.html` — add explicit canvas dimensions\n\nAdd width and height to the canvas element so it has visible dimensions even before JS loads:\n\n```html\n\n```\n\nThese values come from: `GRID_COLS * CELL_SIZE = 12 * 52 = 624` and `GRID_ROWS * CELL_SIZE = 10 * 52 = 520`.\n\n## Conventions\n\n- This is a vanilla TypeScript project with no framework\n- Use ES2022 target\n- Keep changes minimal — only fix the blank screen bug\n- Do not add new dependencies\n- Conventional Commits: use `fix(build):` prefix\n\n## Verification\n\n1.
