/**
 * Accordion: theme styling for the GenerateBlocks Pro accordion. FAQ is its
 * main use (the pattern turns on GB's FAQ schema).
 *
 * globalClass: accordion   (on the GB Pro accordion container,
 *                           variantRole "accordion")
 *
 * Variants:
 *   accordion--boxed     every item is a box on the neutral color with rounded
 *                        corners, instead of a divided list
 *   accordion--numbered  numbered items (01, 02 …): a big number on the left,
 *                        the toggle as the title and a hint line under it that
 *                        stays visible while the item is closed; the answer
 *                        lines up with the title. Not FAQ: no schema.
 *
 * Structure (GB Pro creates it, see the pattern for the exact markup):
 *   .accordion.gb-container.gb-accordion
 *     .gb-container.gb-accordion__item          (variantRole accordion-item)
 *       button.gb-button.gb-accordion__toggle    (variantRole accordion-toggle: text + icon)
 *       .gb-container.gb-accordion__content      (variantRole accordion-content: any blocks)
 *
 * accordion--numbered item (the toggle sits in a row with the number):
 *     .gb-container.gb-accordion__item
 *       .gb-container.accordion-row
 *         p.accordion-number                     (01)
 *         .gb-container.accordion-texts
 *           button.gb-button.gb-accordion__toggle  (title + icon in a circle)
 *           p.accordion-hint                     (one line, always visible)
 *       .gb-container.gb-accordion__content
 *
 * Colors come from the palette: text --font-clr, open/hover --link-clr,
 * lines --border-clr. The toggle's own GB color settings are left empty in
 * the pattern so this file controls the look.
 *
 * Tuning: --accordion-padding-y (18px); numbered: --accordion-number-width
 * (52px, 64px from 990px), --accordion-number-gap (18px),
 * --accordion-number-font (--number-font when the project defines one,
 * otherwise --title-font).
 *
 * Chain animations: animate the whole accordion as one, not the items.
 * accordion--numbered: give the accordion a chainAnimation of type fadeIn;
 * the items then fade in one by one off its .is-visible (CSS delays).
 *
 * Without JS GB Pro's toggles do nothing, so every answer is shown open
 * (html.js comes from the inline script in theme-functions.php).
