   FileCarpenter PDF Editor — v1.9.22 application stylesheet

   One stylesheet for the whole editor. It replaces the four stacked layers
   used up to v1.9.21 (style.css + direct-manipulation.css +
   direct-manipulation-hardening.css + desktop-experience.css), which fought
   each other with !important and made [hidden] unreliable.

   Structure
     1  tokens            8  bench, pages and overlays
     2  base              9  panel (edit / changes)
     3  modes            10  status bar, toast, mode bar
     4  app bar          11  popovers and menus
     5  find bar         12  dialogs and tool palettes
     6  tool rail        13  signature studio
     7  page thumbnails  14  welcome / landing
                         15  responsive, touch, motion

   Swiss-coral system: warm neutral canvas, white paper, ink text, coral only
   for actions, active tools, selection and status.
