/* OverlayV — stylesheet.
 *
 * Everything is driven by the tokens in :root. The light theme re-declares
 * the same names and nothing else, which is why a control never needs a
 * second rule to work in both.
 *
 * A note on type size: the panels are deliberately larger than a typical web
 * app's. An editor is read at a glance while your attention is on the canvas,
 * and small grey 12px labels are the first thing to fail at that.
 *
 * A note on gradients: no text anywhere is painted with a gradient through
 * background-clip. It renders as a solid filled box in several Android
 * webviews, and a headline that turns into a coloured rectangle on a third of
 * phones is not worth the effect. Gradients are used on shapes only.
