/**
 * DA Learn — workspace surface.
 *
 * Light by default, because this is a place people read and think in for
 * twenty minutes at a time, not a console they glance at. The earlier dark
 * treatment looked like a terminal, which is the wrong promise for a lesson:
 * long-form reading wants a quiet paper ground, generous line height and text
 * that is nearly black rather than mid-grey.
 *
 * A dark scheme still follows the viewer's own setting, but it is a calmer
 * one than before — slate rather than black, so it reads as evening light and
 * not as an instrument panel.
