   Editor v3 — the WORKSPACE (C03). Loaded after editor.css; every rule is anchored on #nb.nb-v3 so it
   wins over the embedded-page layout that editor.css still carries for the sheet contents.
   Phone first: a top bar, a full-bleed canvas and a bottom sheet with three snap states (peek · half ·
   full). Wide screens: the canvas takes ≥ 70 % and the tools become a side panel.
