 * shadcn/ui new-york-v4 "neutral" palitrasi (oklch) + ilovaga xos qo'shimcha tokenlar.
 * :root = light, :root.dark = dark (index.html dagi inline skript <html> ga `dark` klassini qo'yadi).
 * OGOH: ushbu faylda ikki turdagi tokenlar bor:
 *   1) 26 ta rasmiy shadcn tokeni (--background ... --sidebar-ring) — QIYMATLARINI O'ZGARTIRMANG;
 *   2) qo'shimcha (semantik/heat/soya/layout/moslik) tokenlar — kontrast WCAG AA (matn >= 4.5:1, UI >= 3:1) tekshirilgan.
 * --muted = FON (shadcn), matn uchun --muted-foreground ishlating. --accent ham FON (hover/tanlangan qator) — havola/matn rangi uchun --info yoki --primary.
