/* Bootstrap Icons (assuming installed in node_modules or available via CDN in usage) */
/* Ideally we'd import from node_modules if using a bundler, but for simple use we can suggest CDN or rely on user including it. 
   However, since user asked to install it, let's try to reference it if we support it. 
   If this is a no-build raw import system, node_modules import might fail in browser without a server handling it.
   But I will add a comment or try to use a relative path if plausible. 
   For now, just keeping CDN backup in mind. */
