/**
 * Crypto Converter v2 — Professional dark gold theme
 * Responsive: mobile-first, works on all displays
 * @since 5.9.2
 *
 * v5.9.7 — Defensive specificity rewrite.
 * ---------------------------------------
 * Every .cc-* selector is now prefixed with .ffe-converter (the root
 * wrapper element). This bumps selector specificity from (0,1,0) to
 * (0,2,0), which beats any parent-level universal reset like
 *
 *     .some-wrapper * { margin:0; padding:0 }
 *
 * …that page editors often drop around a shortcode. At equal
 * specificity the later rule wins, and inline <style> blocks always
 * load after plugin CSS — so without the prefix bump, such resets
 * silently crushed the converter's padding, margins, gaps, and
 * hover states (reported by a user who wrapped the shortcode in a
 * <div class="ac"> with `.ac * { margin:0; padding:0 }`).
 *
 * In addition, this file now declares element-level defaults inside
 * .ffe-converter for `p`, `a`, `table`, `td`, `th`, `ul`, `ol`, `li`,
 * `button`, `input`, `strong`, and `label`. Those match the selectors
 * page themes typically style (`.ac p`, `.ac a`, etc.) and restore
 * the converter's own values — otherwise page-wide element styling
 * would leak through the gaps.
