/* ==========================================================================
   Leviathan Web — brutalist / paper design, matching the landing page's
   visual system (Source Serif 4 + IBM Plex Mono, paper background, hairline
   rules, zero radius, zero soft shadow). The chat surface itself runs dark
   (--bg) like the landing's "terminal" sections, while chrome around it
   (topbar, sidebars) stays on paper.
