/**
 * `<bs-card>` — Bootstrap card container.
 *
 * The host IS the `.card`. Bootstrap's `.card`, `.border-{variant}`, and
 * `.text-bg-{variant}` classes are mirrored onto the host (via `hostClasses`)
 * so that:
 *   1. The host fills its grid cell / parent like a native `<div class="card">`
 *      would (display, background, border, radius all picked up from
 *      Bootstrap's own selectors).
 *   2. Bootstrap's `.card > .card-body`, `.card > .card-img-top`, etc.
 *      child-combinator selectors continue to match across the shadow
 *      boundary, because the shadow root has no wrapping element — every
 *      shadow node and every projected child is a flat-tree child of the
 *      host.
 *
 * @slot - Card body content.
 * @slot header - Rendered in `.card-header`.
 * @slot footer - Rendered in `.card-footer`.
 * @slot image - Image rendered above the body (`.card-img-top`).
 * @slot image-bottom - Image rendered after the footer (`.card-img-bottom`).
 * @slot img-overlay - Content rendered inside `.card-img-overlay` on top of the image.
