/* portal.css — the portal surface (Help centre now; sign-in, account, store
   and cart later): conventional web-app layouts, deliberately distinct from
   the campaign cockpit (design/ACCOUNTS-SYNC-ROADMAP.md section 8). Shares
   only the tokens in tokens.css (colours, spacing, type), never cockpit.css
   layout classes, and every selector is scoped under .portal so a cockpit
   change can't reach these screens or the reverse. */
