/* Renéra · Component layer
   Token-built UI primitives shared across pages, extracted from chrome.css (P2 #4 of
   the architecture-evolution backlog) so they live in ONE place instead of being
   redefined per page. Enqueued globally right after brand-base (priority 21) — every
   page gets these without depending on chrome.css. Page-/section-specific variants
   (e.g. .rn-account .rn-btn in my-account.css) still live in their own files and
   override these by selector specificity.

   NOTE: the auth/error pages use a PARALLEL system (.rn-btn-primary in login-page.css /
   error-pages.css) — that is intentional and NOT consolidated here. See the
   "Auth Style Contract".

   Depends on design-system.css for all --renera-* tokens.
