/* Captcha widget — embedded styles.
 *
 * This stylesheet is loaded by `embed.js` into any third-party page that
 * mounts the widget. It contains ONLY rules scoped to .captcha-card (the
 * widget root) and its descendants (`.captcha-button`, escalation puzzles,
 * post-state cards). It does NOT touch `body`, `:root`, `*`, `a`, `code`,
 * or anything else that would clobber the embedding page's styles.
 *
 * All design tokens are scoped to `.captcha-card` via local CSS custom
 * properties (`--c-accent`, `--c-fg`, `--c-bg`, …). Children inherit
 * them, so escalation puzzles + the post-state outcome card pick up the
 * same palette without needing global `:root` variables.
