The drag-and-drop workspace for building BI122G exercise sheets, served by the Workshop at /projects/exercise-builder. Plain HTML, CSS and ES modules; no build step. It runs entirely in the browser — work in progress lives in localStorage and finished sheets leave as downloads, so nothing is written on the server. This directory is canonical. It began as a deployment target for deploy_builder.sh syncing from the BI122G course folder, and that arrangement has ended; see the README. Includes the sheet's light/dark switch: the stylesheet already carried both themes and followed the reader's system setting, so this adds the control that overrides it — a corner toggle built by sheet.js, applied before first paint by a head script the exporter writes, and hidden in print. The builder's toolbar previews the same attribute on the canvas.

Builder chrome. Deliberately a different visual register from the
|
|
sheet itself — the canvas is the only place the sheet's own design
|
|
appears, so there is never any doubt about what is document and
|
|
what is tooling. The chrome has one look on purpose: the sheet's
|
|
own light/dark switch lives on the sheet, and a dark surround is
|
|
what keeps document and tooling apart in either of them.
