/**
 * Shared Accordion
 *
 * Structural only: trigger, plus/minus toggle, collapse mechanic.
 * Consuming components own their own typography, spacing and panel contents.
 *
 * Tunable per component by redefining these on the accordion root:
 *   --bm-accordion-toggle-size      default 36px
 *   --bm-accordion-toggle-bg        default #FFFFFF
 *   --bm-accordion-toggle-bg-hover  default #EEECE7
 *   --bm-accordion-toggle-ink       default #121A43
 *   --bm-accordion-focus            default #204496
 *   --bm-accordion-max              default 2000px, raise for very long panels
 *
 * Panels are collapsed with max-height, never removed from the DOM, so
 * crawlers that do not execute JavaScript still read the content.
