/*
 * Public cost calculator (/cost-calculator).
 *
 * Extends the shared public-pages.css design language -- the #667eea -> #764ba2 gradient,
 * 12-16px radii, soft indigo-tinted shadows -- rather than starting a second one. Everything
 * here is namespaced .cc-* so nothing leaks into the marketing pages that share the layout.
 *
 * Layout intent: inputs on the left and results on the right on a desktop, with the results
 * panel sticky so the headline figure stays in view while the form is edited; a single
 * column below 1000px with the results moved above the form, because on a phone the answer
 * is what the visitor came for and scrolling past a dozen fields to reach it is the whole
 * problem with calculators like this one.
