/* ========================================
   BareInvestfolio product page
   Everything is scoped under .bif-page. The site header, breadcrumb and footer keep the
   shared cyan glass system (main/header/footer/legal.css); this file only adds the
   app's own stage: pure black bands, #1A1A1A panels and the lime accent.
   Layout uses grid and plain blocks rather than flex for anything that must keep an exact
   box (see the Samsung flexbox note in meta-cipher.css).
