/*!
 * Stake Credit Builder widget styles — Stake Web SDK
 *
 * All rules are scoped to .stake-cb / .stake-cb-* so they don't collide with
 * host page CSS or with other Stake Web SDK widgets (which use their own
 * widget-specific class prefix). Theming is done via CSS custom properties;
 * clients can override them by passing `theme` to mount() (which applies them
 * as inline custom properties on the widget root) or by setting them on a
 * parent element in their own CSS.
 *
 * The .stake-cb class is the widget "namespace" — it carries variables, font,
 * color, and box-sizing only. Visual chrome (background, border, radius,
 * shadow, padding) lives on per-view classes (.stake-cb-card,
 * .stake-cb-history, .stake-cb-overlay-card) so the same .stake-cb class can
 * also be applied to the overlay backdrop without inheriting card chrome.
