This pull request introduces a major update focused on the landing page design, navigation, and build/deployment workflows for the Learning Trade project. The changes include a new SaaS-inspired landing page with multiple new showcase sections, updates to navigation structure and styles, workflow improvements for CI/CD, and several dependency upgrades. Additionally, some unused integrations and files have been removed for simplification.

Landing Page & UI Enhancements:

• Added detailed landing page design specifications in docs/superpowers/specs/2026-04-26-landing-page-design.md, outlining architecture, visual style, and component breakdown.
• Implemented multiple new showcase sections (section1.astro to section13.astro) for the landing page, including ambient backgrounds, glass navbar, enhanced hero section, live statistics, FAQ accordion, glowing CTA, and a minimalist footer. [1] [2] [3] [4] [5] [6] [7]

Navigation & UX Improvements:

• Updated bottom navigation to add a dedicated "Feed", "Explore", and "Upload" tab, improving clarity and accessibility. Also enhanced active link styling for better user feedback. [1] [2]

Build & Deployment Workflow:

• Added a new GitHub Actions workflow (site-build-check.yml) to build and check the site on PRs to key branches, and refactored the deployment workflow (renamed to site-build-deploy.yml) to streamline triggers and remove unnecessary schedules. [1] [2]

Dependency & Configuration Updates:

• Upgraded key dependencies (e.g., astro-seo, daisyui, svelte, unocss, and icon packages) for improved performance and compatibility.
• Cleaned up astro.config.mjs by removing the unused partytown integration and disabling the dev toolbar. [1] [2]

Codebase Simplification:

• Removed the unused google_tag_manager.astro component to reduce complexity.

These changes collectively enhance the user experience, visual appeal, and maintainability of the project.
