/*
 * Public marketing sidebar — the same card component as the blog article
 * sidebar ("On this page" / "Latest articles"), lifted out of the inline
 * <style> in blog/blog_detail.html so more than one page can use it.
 *
 * Class names and metrics are kept IDENTICAL to the blog's so the two
 * sidebars are visually the same component, and so blog_detail.html can
 * later drop its ~165 inline lines and just link this file. The only
 * difference is scope: the blog's rules are all prefixed `.article-detail`,
 * these are not.
 *
 * Two bugs in the original are fixed here rather than copied:
 *   - `.toc-card` used var(--tb-card-bg), which is only defined on elements
 *     carrying Bootstrap's `.card` class. These cards do not, so it resolved
 *     to nothing. Uses --tb-card-bg-custom (defined globally: #fff / #212529).
 *   - Muted text used var(--bs-secondary-color); this build compiles
 *     Bootstrap with the `tb-` prefix so that variable does not exist.
 *
 * Linked after bootstrap/app/custom via `{% block css %}{{ block.super }}`,
 * so no specificity tricks are needed.
