/**
 * EcomCalc Tools — calculators.css
 *
 * Baseline styling for the calculator panel and tools directory grid,
 * using the SAME class names as the EcomCalc theme's design system so
 * the two visually match when that theme is active. Every color/spacing
 * value has a fallback (the `, #hex` part of each var()) so calculators
 * still look clean and usable if a site owner switches to a different
 * WordPress theme — calculator functionality must not depend on the
 * EcomCalc theme being active.
