   Klyxin pricing page — KLX launch-ops.
   Secondary page: extends the shared brand system (tokens.css + site.css).
   Every value references a var(--…) token; logical properties throughout so
   RTL (default) and LTR share one stylesheet. Dark-mode AA overrides mirror
   the dual strategy in site.css ([data-theme="dark"] AND prefers-color-scheme
   with :root:not([data-theme="light"])). Reduced-motion + reduced-transparency
   degrade gracefully.
