/**
 * Three-step block.
 *
 * Scope: rules that set colour, typography or box metrics are prefixed with :is(#top, body),
 * matching assets/css/narthex-gravity.css.
 *
 * Why: Enfold styles links and text through ID-prefixed selectors (#top .av_textblock_section a,
 * #top .main_color a, ...). A class-only selector loses to those however late the sheet loads,
 * which is what painted the CTA label in the theme's link colour on top of the purple button and
 * made it invisible. :is() takes the specificity of its most specific argument, so the prefix
 * buys the ID weight needed to win, while the `body` branch keeps the rules working on a theme
 * that has no #top wrapper. That avoids an !important on every declaration.
 *
 * Layout-only rules (grid, flex) are left unprefixed: no theme competes for those. Visibility is
 * the exception - see the state-visibility block at the bottom, which has to out-specify this
 * file's own CTA rule, not the theme's.

 * These carry the :is(#top, body) prefix even though they are visibility-only, and it is load
 * bearing here for a reason the note at the top of this file does not cover: the competition is
 * not a theme, it is the CTA rule twenty lines above. `:is(#top, body) .narthex-steps__cta:link`
 * scores (1,2,0) and sets display:inline-block. Unprefixed, these selectors score (0,3,0), and an
 * ID beats any number of classes — so display:none lost and every D-day CTA was visible before the
 * event day, including "Voir le direct" to a signed-in member weeks early.
 *
 * With the prefix they score (1,3,0) and win. Keep the prefix on any rule that hides a CTA, and
 * check the specificity rather than the selector length when adding one.
