/**
 * ==============================================================================
 * FILE: styles.css
 *
 * DESCRIPTION:
 * Base stylesheet for the Slither Clone SIO application. Includes global resets,
 * body styling, main menu layout and appearance (buttons, forms, title),
 * notification styles, offline page styling, credits/help panel styles,
 * common UI elements (like buttons, inputs), focus visibility styles, and
 * defines root CSS variables for theming across the application.
 *
 * DEVELOPER GUIDELINES:
 * - Keep comments concise, relevant, and in English.
 * - Explain complex selectors or layout techniques.
 * - Define reusable CSS variables (--var-name) here for consistent theming.
 * - Maintain and update existing comments when refactoring or modifying styles.
 * - Ensure styles are organized logically (e.g., base, layout, components, theme).
