/* ============================================================================
   vb-calc.css — /tools/video-storage-calculator.
   ----------------------------------------------------------------------------
   The page's two instruments: the Record Video sheet with its readout, and
   the crew tape planner on the cream band. Everything here uses vb.css's
   tokens (the stray-colour lock in marketing-pages.test.js covers vb.css; this
   file declares no :root of its own on purpose, so there is nothing to drift).
   A page shell may carry no private <style>, which is why this is a file:
   ten translated shells link the same one and a translator never sees CSS.
   Behaviour is in vb-calc.js; the shell holds the words and the numbers.
