/**
 * ai-chatboxes — SELF-CONTAINED client red chat widget styles.
 * =============================================================================
 * SA-1 wave (architecture correction): "chat is the PLUGIN, not the theme."
 * The plugin must render the client-facing red ArneIron chat widget on its own,
 * independent of the arneiron-g theme + its ds.css. This stylesheet PORTS the
 * minimal red "pix-theme-tone-arneiron" palette + CRT look + the
 * chat-window/launcher/composer/thread/bubble styles out of the theme's ds.css
 * (§8 CHAT block) and SCOPES every rule under `.arnyiron-chat-root` so it:
 *   - is fully self-contained (its own --c-* / --grad-* / --sh-* tokens — never
 *     reads the theme's :root or its body.pix-theme-tone-arneiron class);
 *   - cannot leak onto / collide with the host theme (all rules are descendants
 *     of .arnyiron-chat-root, the only un-prefixed selector is the launcher FAB
 *     + its own crt scrim, both plugin-namespaced);
 *   - matches the EXACT class contract the existing live driver
 *     (public/js/arnyiron-chat-live.js, U03) binds to: .chat-window / .chat-head
 *     + [data-status-bind] + .status-dot / .chat-thread[data-ai-chat-mount] /
 *     .composer + input + .send / .msg + .bubble (--user/--agent) / .alert--error.
 *
 * REVERSIBILITY: enqueued only by Arnyiron_Chat_Widget; removing that enqueue (or
 * deactivating the plugin) drops every rule. No !important, no global resets.
 *
 * @package ai-chatboxes
