/* Kaynko POS — shared stylesheet for new pages (blog, industry-vertical
   landing pages, the repurposed /pos/ page). Tokens match the homepage's
   inline <style> block exactly (index.html) so new pages feel identical
   to the rest of the site; the 4 pre-existing pages keep their own inline
   styles for now rather than being retrofitted onto this file in the same
   pass that adds the new content — a lower-risk choice since this session
   has no way to render and visually verify a cross-page CSS refactor. */
