/*
 * Site.pro Studio — design system.
 *
 * A bespoke, non-Bootstrap design system ported from design/Site.pro Studio.dc.html.
 * All colour, spacing and elevation come from CSS variables keyed off the
 * `html[data-theme]` attribute (dark / light). Accent is fixed to violet.
 *
 * The mockup applied every style inline; here the recurring patterns are promoted
 * to semantic classes (`.spro-*`) so server-rendered Yii2 views stay small and
 * readable. One-off layout tweaks may still use inline styles in a view.
