/* 32-deckstudio.css — the Deck Studio, rebuilt in the library's
 * language.
 *
 * The old studio used a mixture of `.icon-btn`, `.btn-outline`,
 * `.deck-studio-btn` and `.premium-toggle` — none of which matched
 * the library, so it looked like a different app. It is now built
 * from the same primitives as the rest of QUAD: `.icbtn`, `.btnx`,
 * `.sw` (switch-spring), `.sel` (the custom dropdown) and the
 * square, hairline, copper-accented surface treatment.
