Purpose and Entry Point

IRHCD2 is a static, browser-based calculator/reporting application. index.html is the application entry point, loading the UI structure, stylesheets, and JavaScript modules; no server-side runtime or build system is present.

Presentation Layer

The interface is defined in index.html and styled through shared and feature-specific CSS:

• css/styles.css

• css/sidebar.css

• css/ribbon.css

• css/theme.css

These files establish the main application layout, navigation/sidebar behavior, ribbon-style controls, and visual theme boundary.

Application Bootstrap and Control Flow

js/app.js is the likely browser bootstrap/orchestration layer. It connects page lifecycle events and user actions to the UI, calculator, data, and export components. The primary control flow is browser interaction → application coordination → calculation/data processing → UI update or export.

Grounding paths:

• js/app.js

• index.html

UI State and Interaction Management

js/ui-manager.js owns presentation-oriented behavior: reading user inputs, updating visible outputs, and managing UI state or navigation. It separates DOM-facing work from computational logic, keeping calculator code independent of page structure.

Grounding paths:

• js/ui-manager.js

• index.html

• css/sidebar.css

Calculation Domain

js/calculator.js is the core computation boundary. It should receive normalized inputs from the application/UI layer and return calculated results rather than directly owning rendering. This is the primary domain-logic stage and likely feeds both displayed values and generated reports.

Grounding paths:

• js/calculator.js

• js/app.js

Data and Shared Utilities

js/data.js provides application data, constants, lookup tables, or default values consumed by calculations and UI initialization. js/utils.js contains cross-cutting reusable helpers, reducing duplication across the orchestration, calculation, and reporting modules.

Grounding paths:

• js/data.js

• js/utils.js

• js/calculator.js

Reporting and Export Boundary

js/report-exporter.js converts calculated/application state into an exportable report. It is downstream of calculation and should remain distinct from interactive UI rendering, allowing the same result data to support both on-screen display and document/report output.

Grounding paths:

• js/report-exporter.js

• js/calculator.js

• js/ui-manager.js

Runtime and External Dependencies

The repository is client-side only: HTML, CSS, and JavaScript execute in a web browser. No backend services, database, deployment infrastructure, package manifest, or explicit third-party dependencies are represented in the supplied tree. Export behavior, if it creates files or print output, runs through browser capabilities.
