/*
 * Orkyo marketing — shared site stylesheet
 * ------------------------------------------------------------------------
 * Served at the web root as /site.css (Dockerfile root-copy + the vite dev
 * MIME map). Holds the blocks that were duplicated across all 10 marketing
 * pages: reset, body base, .container, the header/nav (now with a responsive
 * hamburger), the footer, and the .demo-banner.
 *
 * Unified breakpoints — DO NOT add new stops in page-level <style> blocks:
 *   phone   : @media (max-width: 767px)
 *   tablet  : @media (max-width: 1023px)   (nav collapses to a hamburger below 1024px)
 *   desktop : default (>= 1024px)  — inline link row, unchanged
 * ------------------------------------------------------------------------
