/**
 * * Styled console logger with chainable, type-safe color and text effects for both `Node.js` (`ANSI true-color`) and browsers (`CSS` via `%c`).
 *
 * @remarks
 * - Chain any mix of foreground colors (e.g. `green`), background colors (e.g. `bgBlue`), and text styles (e.g. `bold`, `italic`, `underline`).
 * - In browsers, styles are applied using `CSS`; in `Node.js`, `ANSI` escape codes are used.
 * - When multiple styles of the same category are chained, the last one wins.
 * - Use `.log(value, stringify?)` to print; set `stringify` to `true` to serialize with `JSON.stringify`.
 * - If you need custom reusable style configurations, use {@link https://toolbox.nazmul-nhb.dev/docs/classes/LogStyler Stylog} class.
 *
 * @example
 * // Simple color
 * Stylog.green.log('Ready');
 *
 * @example
 * // Foreground + background + effect, with JSON stringification
 * Stylog.green.bgBlue.bold.log({ a: 121 }, true);
 *
 * @example
 * // Reusable base chain
 * const base = Stylog.underline;
 * base.red.log('Error');
 * base.error.log('Error');
 * base.bgYellow.bold.log('Caution');
 *
 * @example
 * // Works in the browser console too
 * Stylog.cornflowerblue.italic.log('Hello from the browser');
