/* ChatFlow Account Pool view (#pool-view, design A). Needs tokens.css, components.css and
   chrome.css (.cf-page) first. Page header (one primary: Add Account; New Folder; the rare
   commands in More), the lifecycle summary, the bulk bar, then folders and the accounts
   that are in no folder, each a card of shared rows ordered by lifecycle (Idle, Warming,
   Active, Banned). Colours come from tokens only, so night needs no rules here.

   Status is always a word on a chip in the colour language (COLOUR-TOKENS): Idle grey
   (.chip-idle), Warming amber (.chip-warn), Active green (.chip-ok), Banned red (.chip-bad),
   in the rows and in the summary. Folders, the unfiled card and the skeleton are raised
   surfaces (--shadow-card). Class names are pool-* so the old night layer's .folder-card,
   .folder-head, .empty-state and .flow-list rules never reach this view. */
