/**
 * Converts each style section into a list of rulesets
 * containing the block styles to be appended to the stylesheet.
 *
 * See glossary at https://developer.mozilla.org/en-US/docs/Web/CSS/Syntax
 *
 * For each section this creates a new ruleset such as:
 *
 *   block-selector {
 *     style-property-one: value;
 *   }
 *
 * @since 5.8.0 As `get_block_styles()`.
 * @since 5.9.0 Renamed from `get_block_styles()` to `get_block_classes()`
 *              and no longer returns preset classes.
 *              Removed the `$setting_nodes` parameter.
 * @since 6.1.0 Moved most internal logic to `get_styles_for_block()`.
 *
 * @param array $style_nodes Nodes with styles.
 * @return string The new stylesheet.
