/*
 * KN Phone case study — page styles.
 *
 * Loaded only by resources/views/web/projects/case-studies/kn-phone.blade.php.
 * Every class is prefixed `kp-` and every colour, radius, font and easing comes
 * from the site's own tokens (--c-*, --radius, --font-*, --ease-out), so the
 * page follows the dashboard theme, light/dark mode and RTL without a Tailwind
 * rebuild. Logical properties throughout: the Arabic page mirrors itself.
 *
 * One colour is the store's rather than ours: --kp-store, KN Phone's cyan,
 * used sparingly on the device frames and the client mark so the store's
 * identity sits inside MagnAct's page without competing with it.
