Live demo: https://mohamed3042.github.io/quotation-builder-demo/
An interactive, browser-only case demo by Mohamed Mahmoud. It lets a visitor edit fictional quotation details, see the A4 result update, switch the interface between English and Arabic, and use the browser print path.
This is a clean-room simulator, not the production application. The public repository contains only fresh demo presentation code and fictional sample data. It does not contain or derive from the private desktop product's source, document templates, business branding, customer records, historical prices, catalog data, saved records, private media, or production rules.
Client-side webpage code cannot be hidden from visitors. The safe separation is intentional: the private product remains private, while this limited public simulator demonstrates its UX and product thinking without shipping the real implementation.

The fail-first runner plants four independent defects in disposable copies and requires each owning
gate to turn red before the untouched demo returns green.
Proof artifacts include desktop, phone, Arabic, highlighted-workflow, and one-page A4 print renders.
