/* ==================================================================
   CORTEX9 — shared styles for the static marketing pages
   (public/pricing.html, public/features.html)

   These pages are plain HTML in public/, NOT part of the Vite React
   landing build, so they cannot import landing/styles.css (its asset
   name is content-hashed at build time and there is no stable URL to
   link). This file is the deliberate, self-contained subset of that
   design system — same fonts, same tokens, same class names — served
   from public/ at a stable path both pages <link> to.

   Dark is the default because that is the brand statement on /home.
   Light is opt-in and scoped to :root[data-theme="light"], exactly as
   landing/theme-light.css does it, and reads the SAME localStorage key
   (cortex9_landing_theme) so a visitor's choice survives the jump from
   the homepage to these pages.

   If landing/styles.css tokens change, change them here too.

   The nav is position:fixed, so it contributes no scrollable overflow, and `body { overflow-x: clip }`
   propagates to the viewport: anything that does not fit is simply unreachable. At <=400px that was
   the theme toggle. Shrink to fit rather than wrap — wrapping would change the fixed nav's height and
