*
* "side" keeps the whole game on one screen: the factories on the left, both
* boards — smaller, but both visible at once — beside them. "stack" is the
* classic table: big boards below the factories. The default follows the
* device — a phone starts on "side" (Rémi's phone spec), a desktop starts on
* "stack" (Rémi tried "side" there and reached for the + at once).
*
* The choice is written onto <body data-boards="…">; the page's stylesheet
* does the rest. Persisted like the animation speed, switched from the
* settings panel (the − / + row).
