/**
 * Single compact product card template.
 *
 * Renders the §7.1 "single-compact-card" key against the §8.2
 * canonical ProductCardViewModel array shape produced by
 * {@see \Affilun\Application\Render\ViewModelArrayDumper}.
 *
 * Compact variation of {@see ./single-default-card.php} optimized
 * for inline contexts where vertical real estate is at a premium.
 *
 * What the compact template renders:
 *
 *   - Optional primary image (decorative link, same accessibility
 *     posture as the default template per §20).
 *   - Title (canonical focusable detail-page link).
 *   - Optional brand line (driven by `meta.show_brand`).
 *   - Optional price line (driven by `price.visible`); the
 *     `observed_at_label` and `disclaimer_required` axes are
 *     omitted from the compact surface intentionally to keep the
 *     compact card tall enough for a single product to remain
 *     visually scannable.
 *   - Optional availability label (driven by
 *     `availability.visible`).
 *   - The CTA buttons produced by the ViewModel, using the same
 *     button list as the default card so editor previews and
 *     frontend compact cards expose the same enabled-provider buttons.
 *     The spec §13.3 graceful-degradation rule still applies when
 *     no buttons survive that filter.
 *
 * What the compact template intentionally OMITS vs. the default
 * template:
 *
 *   - Description block.
 *   - Provider badge.
 *   - Disclaimer footer (the disclaimers themselves still render
 *     higher in the containing surface; carrying per-card disclaimer
 *     text in a compact surface would dwarf the cell content).
 *   - Badges block.
 *
 * The template is invoked by
 * {@see \Affilun\Application\Render\ProductCardRenderer}
 * via its include strategy with a single $viewModel local — the
 * read-only associative-array copy of the §8.2 view model with a
 * synthetic `_render_meta` block attached. See
 * {@see ./single-default-card.php} for the exhaustive shape
 * documentation; the compact template only reads the subset
 * documented above.
 *
 * Output rules (per `specifications/rendering-and-template-spec.md`):
 *
 *   - §10 / §15: BEM class strings come pre-tokenized in
 *     `$viewModel['classes']`. The template stamps them verbatim
 *     and never synthesizes its own modifier strings.
 *   - §13.3: Optional sections degrade gracefully — a null /
 *     empty primary image, hidden price, hidden availability,
 *     missing brand, or empty buttons list simply omits the
 *     corresponding region.
 *   - §20: The image link is decorative (`tabindex="-1"`,
 *     `aria-hidden="true"`); the title link is the canonical
 *     focusable detail-page link.
 *   - All dynamic output is escaped with `esc_html` /
 *     `esc_attr` / `esc_url`. The $viewModel array is treated
 *     as read-only by convention.
 *
 * The template exits on direct file access and also returns silently
 * when its single contract input is missing or has the wrong type.
 *
 * @package Affilun
 *
 * @var array<string, mixed> $viewModel §8.2 array shape with `_render_meta` attached.
