THE DETAILS / ACCESSIBILITY
Designed to be used.
Not just looked at.
Dimensional objects are decoration. Clear text, usable controls and readable results come first.
Interface approach
The supplied interface uses semantic headings, labeled fields, visible focus, text-based results and responsive layouts. Warning states include words, not color alone.
Motion
Use the header Motion control to stop decorative animation. A reduced-motion system preference starts without animation. No calculation or result depends on movement, dragging or a 3D effect.
Keyboard and small screens
Use Tab and standard browser controls for links, buttons and inputs. The mobile menu uses an expanded state and the form/result reading order stays consistent.
Exports and limitations
Current estimates can be downloaded as plain text or printed. JavaScript is required for calculation and export. Browser date/time widgets, operating systems, optional contact forms and assistive technologies can behave differently. This is not a certification of complete accessibility compliance.
