/* calculator/ — the estate page around the Paper Tape Calculator.
   Only the readable bands under the app (#about, #calculators, #tape, #exports).
   The app's own rules live in calculator.css, every one scoped under #ptc-app.
   Every colour is a site.css token, so the dark edition follows dark.css. */
