/* ===========================================================================
   Guidebook — the reading surface
   ---------------------------------------------------------------------------
   Guides and policy pages deliberately do NOT look like the app. Tool pages
   are workspaces: sidenav, panels, forms, things to act on. These pages are
   documents: one column, serif body text, a sticky contents rail, and no app
   chrome competing with the words.

   Everything is namespaced `gb-` and lives under `.gb-root`. This file is
   loaded AFTER application.css in the guide layout, which matters: the soft-ui
   theme ships unlayered `h1 { font-size: 3rem }`, `a { color: inherit }` and
   `.text-slate-400/500/700/800` rules that beat Tailwind's own utilities
   regardless of specificity. Rather than fight that per-element, the guide
   surface simply restates what it needs here, later in the cascade.
