/*
 * Icon badge — glow border at rest, revolving gradient ring on card
 * hover. Three nested layers:
 *   .feature-icon        the box itself; clips its own oversized spin
 *                         layer via overflow:hidden, sized down to a
 *                         thin ring by the 1px padding "gap".
 *   .feature-icon-spin   the conic-gradient ring — absolutely
 *                         positioned and oversized (inset:-70%, well
 *                         past the box), which is what turns the
 *                         gradient's colour bands into a thin sweeping
 *                         arc once clipped, rather than a full circle.
 *                         Hidden/paused at rest.
 *   .feature-icon-inner  the visible icon face, sits above the spin
 *                         layer (z-index:1) and never itself moves.
 * The hover trigger lives on .feature-card (the ancestor), not the
 * badge, so the whole card is the hit area and the ring reacts even
 * when the cursor isn't directly over the icon.
