/* ============================================================
   customize-shell.css — "Customize Shell" for pages/customize.html
   (see customize-layout-suggestion.md).

   One skeleton shared with series-shell.css / global-search.css:
   identity strip -> sticky control zone (text tabs) -> two column
   desk (option panel + docked live preview rail) -> sticky save bar.

   Tokens: the neutral --ss-* scale from css/series-shell.css, which
   is loaded BEFORE this file. Everything here is scoped under
   .cz-shell so no other page shifts.

   Spacing scale: 4 / 8 / 12 / 16 / 24 / 32 / 48px only.
