Rationale

Why this compiler exists.

In data-driven business applications, backend schemas and metadata already exist as JSON. Forcing them into template strings or heavy framework components causes synchronization friction and security headaches.

The 3 Traditional Approaches & Their Flaws

1. Brittle String Templates (Handlebars, Mustache, template literals)

Fragile escaping, difficult nested iterations, and security risks with innerHTML. Custom helpers must be registered just to do simple checks or loops.

2. Heavy Component Frameworks (React, Vue, Angular)

Huge bundle sizes and build toolchain requirements (Webpack, Babel) just to render data-driven forms or grids. Data schemas become tightly coupled with framework lifecycle hooks.

3. Multi-File Orchestrator Synchronization Drift

Splitting code across instruction files, template files, and schema files creates synchronization drift. Changing one field name forces edits across 4 different files.

The json-to-spec Breakthrough: Reduce everything to strictly 2 files: structure.json (the visual blueprint) + data.json (the business payload). The compiler marries the two and emits clean, valid spec JSON in under 0.5ms.
