/* K-F · Portal Deck — deck/reader components.
   Composes INSIDE the shared portal chrome (public/css/style.css): the global
   reset, body, links, top-nav, footer, skip-link and focus rings all come from
   style.css. This file only styles Deck/Reader-specific components and maps its
   semantic var names onto the shared portal palette so the Deck looks like it
   belongs to the same portal. Text-first, GPU-free, WCAG-AA. */
