Release 0.3.0 - UX, Performance & Hugging Face Pivot

[GehDoc]

This release marks a major architectural refinement and security hardening phase. After a brief trial with Gemini 1.5, we have successfully pivoted back to an enhanced Hugging Face integration while retaining all planned UX and data model improvements.

🚀 New Features & Enhancements

• Hugging Face Llama 3.1 Integration: Restored as the primary inference provider, ensuring reliability and sustainability.
• Enhanced System Prompt: A refined "Fact-First" prompt enforcing strict JSON output, high-precision geographic data (City, State, Country), and dynamic localized map links.
• Top-Level Interactive Maps: Automatic transformation of Markdown links into secure Google Maps iframes, placed at the beginning of itineraries with robust URL encoding (handling commas and spaces).
• Standardized Titles: Enforced the pattern "[Destination]: [Catchphrase]" for consistent branding in the trip navigator.
• Rich Prompt Input: Transitioned to a textarea in the GenerationForm to support detailed, multi-line trip descriptions.
• Trip Data Model v2: Implemented a structured schema (title, start, stop, content, prompt) with a robust migration path from v1.

🛡️ Security & Integrity

• Strict Markdown Sanitization: Integrated rehype-sanitize with a whitelist-only policy. All raw <iframe>, <script>, and potentially malicious HTML from the AI are strictly blocked.
• HTML Validation: Fixed React 19 hydration and nesting errors (e.g., ensuring <div> elements are not nested inside <p> tags during markdown rendering).

🛠 Visual & UX Refinements

• Typography Overhaul: Enhanced the prose styles with explicit Tailwind utility overrides. Section headers (###) now feature borders and distinct scaling.
• Redundancy Cleanup: Removed duplicate titles and unnecessary labels (like "Google Maps:") to achieve a cleaner, more professional card layout.
• Performance Optimization: Applied React.memo to all major presentational components to eliminate unnecessary re-renders.

🧪 Quality & Documentation

• E2E & Unit Testing: Fixed and isolated the E2E test suite on a dedicated port (3002). 31/31 unit tests and all E2E tests passing.
• Full Spec Archival: The entire refinement lifecycle is documented and archived in specs/completed/.
