/*
  OpenBook quick calculator pre-V3 bridge.

  Status: review draft only. This file is linked to a small pilot group of
  production quick calculators, but it is not yet a broad or permanent V3
  standard. It captures common patterns proven in recent UI/UX V3 calculator
  updates so they can be tested before any wider migration.

  Intended load order, when piloted:
  quick-calculator.css -> quick-calculator-v2.css -> quick-calculator-pre-v3.css
  -> app-local CSS for exceptions.
