   EDITAKU — Studio (laboratoire)
   ---------------------------------------------------------------------------
   3-zone layout : top bar / left sidebar (steps) / workspace / right panel.
   Built on top of tokens.css + components.css. Legacy variable aliases kept
   so the existing per-step inline CSS (character grid, snippet grid, etc.)
   still resolves without rewriting every selector.
