/* ==========================================================================
   legal.css — Long-form legal documents (Privacy, Terms)
   Levii Portal · Design System

   Builds on .prose (typography.css). Adds a document shell with a sticky
   table of contents, a plain-language summary card, callouts, a definitions
   grid and a closing contact card. Zero hardcoded colors/spacing — all tokens.
