Semantic HTML5, CSS and vanilla JavaScript power a dependency-free frontend. SVG is used for the favicon. Hash-based navigation connects the screens. Rule-based scoring evaluates budget, timeline, workflow keywords and inquiry detail. Local rules classify intent and simulate priority routing; templates produce follow-up drafts. Browser Session Storage retains local demo changes, with a fallback when storage is unavailable. Reserved
example.com addresses and explicit sample labels distinguish demonstration data from customer records.
