/*
 * Kurumca design system: tokens, type, controls. Shared by the marketing site, portal and admin.
 *
 * Rules this file enforces (kept here so pages cannot drift):
 *  - Color: cool neutrals with a faint blue cast + ONE accent, the brand blue of the product icon.
 *    green / amber / red exist only as status colors. No pure #000 / #fff.
 *  - Shape: one scale. Controls 10px, panels 16px, large media 22px, status pills fully round.
 *  - Motion: transform and opacity only, and only inside prefers-reduced-motion: no-preference.
 *  - Themes: light and dark from the same tokens; `data-theme` on <html> overrides the OS setting.
