/*
 * AI Blog Writer — layout components for posts written in the HTML format.
 *
 * Every rule is scoped under .aibw (the <article> the writer wraps a post
 * in), so nothing leaks into the theme, and the extra class outranks theme
 * element rules such as zebra-striped tables. Colours follow the site: the
 * accent is Elementor's global primary colour, else the block theme's primary
 * preset; neutrals derive from the text colour, so light and dark themes
 * both work. The class vocabulary matches apce_html_format_rules().
