/* ==========================================================================
   DevTools — dashboard shell
   --------------------------------------------------------------------------
   Fonts and tokens come from assets/tokens.css (loaded first by index.html),
   the same file every tool imports through tools/main.css, so the shell and
   the tools cannot drift apart. This file only lays out and skins the shell:
   sidebar, home screen, command palette, dialogs and the tool frame.

   Finish: flat console — solid surfaces, 1px purple-tinted hairlines,
   neutral elevation, 6 / 8 / 12px radii. Purple marks the active item;
   yellow is kept for the single strongest accent (current-tool marker,
   pinned state, key caps).
