Cinderline Client Portal Starter is a self-contained HTML, CSS and JavaScript front-end demonstration for personal or internal business prototyping. It includes responsive CSS layouts, a project-status rail with simulation controls, four fictional deliverable records (initially three ready and one pending), a local message composer/draft preview, an onboarding checklist with progress, editable fictional demo data and CSS color tokens with documented contrast checks. No build system or paid framework is required; the included source makes no hidden network calls. This is not a hosted or production-ready client portal. No backend, authentication, access-control or encryption system, real client files, live uploads, message/email delivery, payments or hosting is included. The listed project deliverables are fictional UI records, not additional customer assets in the download. Demo interactions live in memory and reset on reload/reset; retain any drafts you need before closing. No security, privacy or full accessibility certification is claimed. Actual screenshots show the delivered HTML. Original mockup covers retained inside the ZIP are concept illustrations, not additional implemented interfaces or security/accessibility guarantees. License: one limited, non-exclusive, non-transferable license for the buyer’s own personal or internal business use. You may edit the files for that use. No reselling, sublicensing, redistribution, ZIP/file sharing, marketplace upload, standalone client handoff, sale of modified versions, authorship claims or use to create a competing template, pack, course or software product. Limited portfolio screenshots or outcomes may be shown only without exposing downloadable source files. Ownership remains with the seller; see the unchanged LICENSE.txt for full terms.
