/**
 * AI Assistant Chatbot — Ghootmee AI public-facing widget styles.
 *
 * Every selector is namespaced under .gai-chatbot- to minimize the
 * risk of colliding with theme or other-plugin styles, per the
 * plugin's CSS isolation requirements. Colors/sizes are driven by CSS
 * custom properties set inline by chatbot.js from admin-configured,
 * already-validated Appearance settings — nothing here hard-codes a
 * color/size that Appearance is supposed to control.
 *
 * A defensive `all: initial` boundary is intentionally NOT used here
 * (it was in the v0.1.0 placeholder) because it also resets properties
 * the widget itself needs to inherit or set (box-sizing, font
 * smoothing) and fights with the explicit resets below; explicit
 * property resets on each namespaced class are more predictable.
