 *
 * Why !important: Astra (and several other themes) target
 * `.entry-content > *` with high-specificity margin rules. Our
 * step content lives in `.tsn-step__content`, NOT `.entry-content`,
 * so theme rules don't apply — and core block CSS resets
 * Media & Text margins to 0. The result without these overrides
 * is consecutive action blocks butted right up against each other
 * with no visible boundary. !important here just stakes a claim
 * over a CSS rule that hasn't been claimed by anything else.
 */

/* Zero out any inherited margin so we control spacing exclusively
 * from the rules below. Reset only direct children of the step
 * content wrapper; nested elements (paragraphs inside Media & Text
 * content columns, etc.) keep their own margins. */
.tsn-step__content > * {
    margin-top: 0 !important;
    margin-bottom: 0 !important;

/* Spacing + visible divider between consecutive blocks. The `> * + *`
 * selector matches every direct child that has a sibling before it,
 * so the very first block (the YouTube embed) gets no spacing or
 * border above it — separators only appear BETWEEN sections.
 *
 * Generous spacing + a 2px line is intentional: the previous 1px
 * line at 36px+32px was still being lost in dense pages. Total
 * separation here is 48px above + 2px line + 40px below = 90px
 * of unmistakable boundary between actions. */
