Project description:
"I want to publish a dedicated web page tool that mirrors the look-and-feel of the reference link ([login to view URL]) while being entirely original in code and copy. The page needs two tightly-linked parts:

1. Interactive calculator
• Runs entirely in the browser (JavaScript, React, Vue, or plain JS—your call).
• Accepts principal, rate, time, and compounding frequency and instantly updates results.
• Displays a clean line or bar graph that visualises the growth over time.
• Generates a downloadable PDF or CSV report summarising inputs, yearly balances, and totals.
• Includes a lightweight sign-up / log-in flow (email + password or social) so users can save their calculations for later.

2. Long-form explanatory article
• Similar structure and length to the sample page, but written from scratch in fluent, SEO-optimised English.
• Explains what compound interest is, provides real-world examples, and guides readers on using the tool.
• Headings, meta tags, and internal anchor links ready for WordPress or any standard CMS.

I’ll supply hosting and domain; you supply all front-end code, a simple back-end (Node, PHP, or Python) for authentication and PDF/CSV generation, plus installation instructions so I can deploy in one step.

Please outline:
– Frameworks/libraries you plan to use
– Time required for a functional prototype and for final polish
– At least one live example of a calculator or data-visualisation project you’ve built

Clean code, responsive design, and clear documentation are must-haves." (client-provided description)
