Summary of App Behavior

This app is a single-file JSON viewer that takes a Wikipedia-style JSON file (one hosted on producingtechnology.com) and turns it into a styled article reading experience. The user pastes a JSON URL into a text input and clicks "Load JSON," or clicks "Use Sample Path" to load a default example. The app then fetches the file, reads the HTML stored inside parse.text["*"], and re-renders it as a cleaner article with a topic title, section navigation, summary counters (sections / images), and a visual gallery. Before anything is loaded, the main area shows "No article loaded · Waiting for a JSON URL" and the counters sit at 0.

Things That Didn't Work How I Expected

• The "Use Sample Path" button is the fastest way to see the app work, but there's no visible indication of what sample article it will load until after it's fetched — a small preview label would set expectations.
• The input only accepts URLs hosted on producingtechnology.com, which isn't stated near the field itself; if you paste a normal Wikipedia API URL, it's unclear whether it will silently fail or reject you.
• There's no visible loading spinner or error message area, so if the fetch is slow or the JSON is malformed, the user is left staring at the "Waiting for a JSON URL" placeholder with no feedback.
• "Quick navigation" appears as a heading before any article is loaded, even though it has nothing to navigate yet — it should either be hidden until content exists or show a placeholder hint.

Prompt to Improve the App

Improve the Text Media JSON Viewer with the following changes:

1. Add a loading state (spinner + "Fetching article…" text) while the JSON is being retrieved, and a clear inline error message if the fetch fails, the URL is off-domain, or parse.text["*"] is missing.
2. Show what "Use Sample Path" will load by displaying the sample article title next to the button, and validate the URL field in real time with a hint explaining that only producingtechnology.com URLs are accepted.
3. Keep a small history of recently loaded JSON URLs in localStorage and show them as clickable chips below the input so users can quickly revisit past articles.
4. Hide the Quick Navigation, Topic, Sections, and Images panels until an article is actually loaded, and make section links scroll smoothly with the active section highlighted as the user scrolls.
5. Add a lightbox to the visual gallery (click to enlarge, arrow keys to navigate) and a reading-mode toggle with adjustable font size and a light/dark theme.
