/*
 * Nahnu Code Block — frontend styles.
 * All custom properties are prefixed --nahnu-code-block- and scoped to
 * .nahnu-code-block so this never leaks into (or collides with) other
 * plugins' styles.
 *
 * The actual color values (light default, OS-dark, per-block manual
 * override, and any theme/plugin integration via selectors) are generated
 * dynamically by PHP — see Nahnu_Code_Block::nahnu_code_block_generate_theme_css()
 * in includes/class-nahnu-code-block.php — and injected as inline CSS
 * right after this stylesheet, so the whole palette is filterable via the
 * `nahnu_code_block_theme_variables` hook without editing this file.
