Every lucide icon is its own module, and the plugin icon lookup reaches all
of them by name from the navigation. The bundler therefore put each icon
another chunk also uses into a chunk of its own: 187 files of a few hundred
bytes, each one a request on a first visit and an entry in the precache.
A `vendor-icons` group collects them. The first load asks for 32 script
files instead of 224 (the bytes stay the same, 3.9 MB before compression),
and the service worker installs 460 files instead of 652. With 50 ms added
to every response the login page reaches DOMContentLoaded in 0.5 s
instead of 3.8 s.
