/*
 * Fawri Developer Portal — shell chrome stylesheet (story portal-shell-chrome).
 *
 * Design-TOKEN reuse, not operator CONTENT reuse: the custom-property VALUES below are
 * copied from the platform's ADR-007 design-token system (operator-portal's
 * tokens-primitive.css / tokens-semantic.css) so this externally-facing portal is
 * visually consistent with the rest of the platform. No operator label, role name,
 * severity-chip wording, or tenant theme is reused here — only raw color/spacing/
 * radius/typography values, renamed to a shell-local, generic vocabulary.
 *
 * No @import / url() to any external host, no CDN font — system font stack only.
