I am providing a complete front-end project written in pure HTML, CSS and JavaScript. The app already works as intended, but most of the code was generated with ChatGPT and it now needs a careful human touch. What I need from you • Read through every file, refactor where necessary and replace AI-styled naming with clear, conventional names. • Keep every feature, interaction and visual detail exactly as it is; the behaviour in the browser must remain unchanged. • Remove redundant snippets, organise the structure logically, and add concise comments where they improve readability. • Run the project after each change to be sure there are no console warnings or errors in any modern browser. Deliverables 1. A cleaned, fully working set of HTML, CSS and JS files that mirrors the current functionality. 2. A short change log noting any structural shifts or important renames. Acceptance criteria • No functional regressions; side-by-side testing shows identical behaviour. • No console errors or warnings. • Code passes basic plagiarism and AI-detection checks as unique human-written work. Send the updated files and the change log once everything is solid.
