/* ==========================================================================
   tool-public-editorial.css

   Editorial layer for the public tool page (NewToolPublicPage.cshtml). All
   `.tp-*` selectors and the published-guide article live here. Split out
   from `tool-public.css` (chrome/runtime/workspace/rail) so the editorial
   styles can ship lazily — the workspace paints first, the long-form guide
   + sidebar + editorial cards stream in via media="print" → "all" swap.

   Pure CSS only (no Tailwind directives). Token references resolve via the
   public-site bundle's :root variables, which load synchronously upstream.

   See plan: kind-enchanting-storm.md Phase B1.

   MOBILE BOTTOM-SHEET RAIL (<720px)
   On narrow viewports the right-rail overlay is repositioned as a
   bottom sheet anchored to the viewport floor. The icon strip acts
   as a tap handle, and `:focus-within` (any keyboard / tap focus on
   a child control) reveals the rail content sliding upward.
   This replaces the side-slide overlay pattern, which obscured the
   workspace on small screens.
   Pairs with `viewport-fit=cover` in `_SharedShellLayoutBase.cshtml`
   for safe-area-inset support on iOS Safari.
