/* Portal shell — login screen, sidebar nav, iframe stage. Portal Phase 1 (2026-08-06).
   Loaded after tokens.css + shared.css. Deliberately its own small vocabulary (.shell-*)
   rather than reusing omd.css/transaction.css's component classes — this page has a genuinely
   different layout (sidebar + iframe stage) from either module, so there's nothing real
   to share beyond the tokens already shared. */
