 ## ANTI-PATTERNS (THIS PROJECT)
 
 - **DO NOT** use `output: 'standalone'` in dev mode (breaks HMR)
 - **DO NOT** hardcode contact info - use `siteConfig` from `@/data/site-config`
 - **DO NOT** add tests - project has no test infrastructure
-- **DO NOT** use `as any` or `@ts-ignore` - strict mode enabled
+- **DO NOT** use `as any`, `@ts-ignore`, `@ts-expect-error` - strict mode enabled
+- **DO NOT** modify CSS unless necessary - preserve existing design

+**Location**: `public/images/`
+
+**Optimization**:

+- Always provide `alt` text in Thai
+- Specify `width` and `height` to prevent layout shift
+
+## SEO
+
+**Metadata**:
+- Thai language meta tags
+- Open Graph tags for social sharing
+- Twitter Card support
+- Structured data (JSON-LD) for LocalBusiness
+
+**Thai URLs**:
