/* marketing-btn.css — the ONLY part of nxcart-components.css the public
   marketing pages (home + _shared scaffold: pricing/about/contact/blog)
   actually use: the .nx-btn family. Extracted verbatim from
   nxcart-components.css (the single source of truth — keep in sync if the
   button design changes there) so the marketing site no longer loads the
   full ~130KB admin component stylesheet just for buttons.

   Depends only on --nx-* tokens from nxcart-tokens.css, which the marketing
   pages still load alongside this file. Do NOT add non-button rules here —
   if a marketing page needs another nx_* component, add it to this file
   (and keep it in step with nxcart-components.css). */
