How it’s built
One schema. One math engine. Many pages.
Every calculator is a record. The record drives the page, the math, the SEO — and tomorrow’s redesign of all of it at once.
Schema-driven
Inputs, outputs, copy, FAQs, and search intent live as data. Pages render from the record, not one-off code.
Single math engine
A switch on slug returns computed outputs. New calculator = new record + new case — never a UI rebuild.
