   -------------------------------------------------------------------------
   An app page: it takes the site chrome (strip + crumbs + footer) and
   nothing else, because its own editor fills the viewport. Layout is a
   three-column shell under the chrome — tool rail, board, panel — that
   collapses to a stacked sheet on narrow screens.

   Everything here is prefixed `ps-`. The `pw-` tokens come from
   /assets/pw/stage.css and are read, never redefined, except the two
   local aliases below.

   The sheet is built as SVG sized in millimetres, with a viewBox in the

   prints 203.2 mm wide at 100% scale, on any browser, without depending
   on a CSS pixel ratio that browsers do not agree about. The peg pitch
   therefore lands where the board's holes actually are.

   @page has no margin because the sheet already carries its own — the
   browser's default margin would otherwise shrink the artwork to fit and
   silently break the scale. The margin box is drawn by the sheet itself.
