Summary of App Behavior

The destination page is a very lightweight JSON viewer with heading My App Viewer. It fetches a remote JSON payload and renders selected fields into plain HTML content.

Initial state shows a temporary Loading... message.
On successful fetch, it renders app metadata for Synapse (1.0.0), including description and owner.
It lists features with enabled/disabled status and prints parts of the tech stack (frontend/backend/database) and deployment environment + region.
If fetch fails, it falls back to a simple error message: Error loading JSON.

Things That Did Not Work As Expected

No meaningful interactivity: the page behaves as a static renderer after load (no controls to filter, sort, expand, or inspect JSON deeply).
Incomplete data coverage: the JSON contains nested details (for example feature subfields and infrastructure/scalability), but those are not shown in the UI.
Minimal error UX: error handling is only a plain text fallback and does not show status code, retry option, or recovery guidance.
Document structure is basic: there is no page-level title metadata in a proper <head> section, which weakens usability and accessibility.

Prompt To Improve The App

You are improving an existing single-file JSON viewer app (plain HTML/CSS/JS). Keep it dependency-free, but upgrade it to feel like a complete product:
1) Add a proper HTML document structure with semantic landmarks, page title, and accessible headings.
2) Preserve current behavior (fetch remote JSON and render core fields), but also render nested details (feature subproperties, infrastructure, scalability).
3) Add interactive controls: expand/collapse sections, search/filter by feature name, and copy-JSON button.
4) Improve error handling with visible status, retry action, and fallback messaging that includes HTTP error context.
5) Add responsive styling (cards, spacing, readable typography) while keeping everything in one HTML file.
6) Return the full updated HTML file only.
