/*
  grade_split.css — "Split Screen" Grade theme (Grade.layout_theme="split").
  Deliberately mirrors static/assets/css/subject_split.css's design (same
  "Arsha Corporate" tokens, same sticky-left/scrolling-right shape) but kept
  as its own file/prefix (.gsp, not .spl) — same one-file-per-template
  convention as subj-min/mkt/spl elsewhere, so each theme's CSS stays
  self-contained even where two themes happen to look alike. Every rule is
  ".gsp .gsp-x" (two classes) to avoid the single-class specificity bug that
  bit .mkt-btn in marketing_node.css.
