/**
 * Digital Employee Framework — Chat Trigger Button (main document)
 *
 * Styles for the [def_chat_button] shortcode and `def_core_chat_button`
 * action hook. The floating trigger button (`.def-cc-trigger`) lives
 * inside the Customer Chat Shadow DOM and is styled by the loader's
 * inline <style> block — those styles cannot reach the main document.
 * This stylesheet mirrors that visual design for the main-document
 * button so theme-header / shortcode-placed buttons get the same look.
 *
 * Color variables `--def-chat-btn-color` / `--def-chat-btn-hover` are
 * injected via wp_add_inline_style on every frontend page from the
 * existing Chat Settings options (def_core_chat_button_color and
 * def_core_chat_button_hover_color), so the same admin controls drive
 * both the floating button and the shortcode-placed button.
