The Cubic Equation Solver has been updated. List of changes: * Added a dynamic step-by-step solution section for cubic equations; * Added a unified theory section with the depressed cubic formula, Cardano coefficients, discriminant, and case conditions; * Localized all step labels and explanatory texts via i18n (EN/RU); * Improved the readability and structure of the explanation area for a more cohesive learning flow.
