/* =========================================================================
   PREPIQ BOOT SEQUENCE  (embed on the IQ Books stage)
   =========================================================================
   PrepIQ's promise is a finished set of working papers, so the opening is the
   set assembling: sheets arriving one after another, squaring up into a bound
   file, index tabs appearing down the edge, and the spine closing over them.

   The sheets are the ones PrepIQ actually builds — extended trial balance,
   lead schedules, fixed assets, capital allowances, tax computation, notes —
   and the client and year end are the real job. Bronze throughout, which is
   PrepIQ's colour across the suite.
