/**
 * Post-processes HTML serialised from the Lexical editor, converting class-based
 * text formatting to inline styles and applying brand-consistent defaults to all elements.
 *
 * Specifically:
 * - Converts Lexical's text format classes (textBold, textItalic, textUnderline)
 *   to their inline style equivalents
 * - Applies the Sage UI font family to all elements
 * - Applies link styles (color, cursor, underline) to anchor elements
 * - Preserves any existing inline styles set by Lexical (e.g. white-space: pre-wrap)
 *
 * This ensures the output HTML is portable and renders correctly in contexts where
 * the Lexical stylesheet is not present, such as email templates or external consumers.
