/* ─────────────────────────────────────────────────────────────
   The IDE as a full-window app (laptop and desktop widths).
   Loaded after styles.css on /ide/ only. The phone layout (900px and narrower) is untouched.

   Regions, after VS Code 1.142.0's workbench (docs/reference/vscode.md, section 1):
     title bar · run bar
     activity bar (48px) │ side bar (resizable, hideable) │ editor over terminal panel
     status bar (22px)
   Colours still come from the tokens on .ide in styles.css, so a new theme (#4) is one block there.
