   Hisaab — Smart calculators for India.
   PREMIUM DARK-FIRST theme: teal #15a8a0 -> emerald #10b981.
   Dark is the DEFAULT (:root). Light is opt-in via the toggle
   (html[data-theme=light]) and persisted in localStorage.
   All existing class names + var names (--acc/--acc2/...) are
   preserved so every calculator's logic keeps working unchanged.
   Inter font. Inline SVG icons. Glassy rounded premium cards.
