Code Splitting & SEO Fixes

Code Splitting

• 41 pages now lazy-loaded on demand with loading spinner fallback
• Vendor chunk splitting — shared libraries cached separately from application code
• Initial bundle reduced from 1,020 kB to 84 kB — pages load only the JavaScript they need
• Faster first paint and reduced bandwidth for all users

DNS & Security

• DNS CAA records added — only the authorised certificate authority can issue SSL certificates for SpeyBooks domains
• security.txt contact and policy URLs corrected
• robots.txt added to application and API domains to prevent search engine indexing of authenticated content
