/*
  The ZenAI page (D1, TO-55): every brief, grouped by report, with its filters.

  Its own stylesheet, like zen-drawer.css. The page carries .tomo-face, so every token below (and
  the dark palette) comes from tomo-face.css. Nothing here invents a colour. One centred column,
  as the chat has it (Ro, 23 Oct 2026); inside it, each brief is the kit's collapsible row
  (TomoCollapsibleRow, Ro, 26 Oct 2026): compact collapsed, the detail on expand, one list at every
  width, the same pattern as Connections and Settings. The row's own styles are in tomo-face.css.

  Hosts include it after tomo-face.css:
    <link rel="stylesheet" href="_content/Tomo.Face/zen-page.css" />
