/* KPNet, design D ("Desk"): quiet grey sidebar, one centred column, the composer is the hero.
   K+P blue only for primary buttons, focus, links, activity and the logo; status lights use red, amber and green.
   Type (README 2.1): one face, Segoe UI, code in Cascadia Mono; five sizes and two weights, used only through the
   tokens below. Bold is Segoe's real semibold. Copy keeps the KP email font (chat.js). Text size (core.js) zooms all of it. */
