/*
 * converter.css — styles for the `.cw` live currency-converter widget
 * (see build.py: build_converter_widget, and shared/converter.js).
 *
 * Visual language matches `.answer-box` in site.css: white card, gold
 * inline-start accent, soft shadow, same radius/spacing tokens. Relies on
 * the :root custom properties defined in site.css (--red, --gold, --dark,
 * --surface, --border, --radius, --shadow) — this file is always loaded
 * alongside site.css by build.py, never standalone.
 *
 * Logical properties (inline-start/end) are used throughout instead of
 * left/right so the widget mirrors correctly on the site's RTL locales.
