JASON (JSON Manager) por StefanoStem

What is it
A focused side-panel tool for:
- Collecting JSON-like payloads from active pages,
- Storing and organizing snippets in tabs,
- Validating/formatting/minifying content,
- Comparing two payloads with visual diff guidance.

How you use it
Three core modes:
- Store: tabbed JSON workspace (edit, search, fold, format, save, download).
- Compare: two JSON fields side by side, run comparison, inspect line/word-level diffs, and confirm perfect matches.
- Capture: run scan on current tab, review results, store or compare selected captures.

Why
- Reduces context switching between devtools, editors, and scratchpads.
- Keeps JSON workflows in one persistent place.
- Improves review speed with inline compare visuals and searchable content.

UI/UX
- Local persistence with fast reopen behavior.
- Light/dark theme support.
- Real-time size/validation feedback.
- Search across workspace content and capture content.
- Scan flow includes user feedback and retry behavior for common tab-readiness timing cases.

Privacy and architecture
- No analytics, no third-party telemetry, no external data transmission.
- Data stays in browser local storage.
- Plain JS architecture with shared source + browser-specific manifests/background scripts.
- Deterministic build pipeline with manifest sync checks.
