/*
 * Kitchen configurator — the stylesheet.
 *
 * Room studio's design language, carried over: dark glass panels, a dock of
 * section buttons at the bottom centre, a control panel on the right that
 * becomes a bottom sheet on a phone, icon buttons and a quality select at
 * the top right, a loading screen with a real progress bar and a veil for
 * discrete changes. Every target is 44 px or more; the safe-area insets are
 * honoured. Everything the room had that a kitchen has not (the seat grid,
 * the display readout, the transport) is gone, and the kitchen's own pieces
 * (the unit strip, the floating and dimension labels, the floor disc, the
 * price pill and summary table, the image swatches) are at the end.
