/* Study MCP web UI. Built from Redo Queue's stylesheet (redo-tracker-v2, apps/web/src):
   styles/tokens.css + fonts.css + base.css, App.module.css (header, tabs, badge, chips),
   components/Blocks.module.css (grouped lists with the left stripe, rows, rating buttons),
   features/today/Today.module.css (status line), features/agent/Agent.module.css (connect steps,
   activity rows), features/settings/Settings.module.css. CSS-module names are translated to plain
   class names; the comments say where each block came from.

   Redo is light only ("Paper" tokens; text colours darkened so every text/background pair meets
   WCAG AA 4.5:1), and so is this page. */
