March update

First monthly update for CREA.MBA. During March we focused on adding capture tools, improving performance, and polishing details that make everyday development smoother.

Lead capture

• New lead capture system with form, validation, and email notification.
• Integrated with feature flag, admin panel, and i18n (EN/ES).
• Full admin management: listing, filters, and lead deletion.

Analytics

• Google Tag Manager (GTM) support alongside GA4 — configure one, the other, or both.
• Analytics module refactored for clarity and less code.

Performance

• YouTubeEmbed component — lazy-loads the iframe on click, saving ~815 KiB of initial load. Uses high-res thumbnails with automatic fallback.
• Cache headers for static assets and Next.js bundles.
• .dockerignore added to reduce Docker build context.

Security

• Ad platform domains added to CSP — Google Ads, Meta, and TikTok ready to use without touching the configuration.

Admin

• Record deletion for waitlist, newsletter, and leads from the admin panel.
• Blog hidden on landing when no published posts exist — avoids empty sections.

UI

• Marketing component colors fixed — removed hardcoded colors to respect theme variables (light and dark mode).

Documentation

• New known issues document (i18n locales, build performance, new Date in RSC).
• Documented the route disabling technique with _ prefix for bundle optimization.
