 * Brand logo for Moldovan M-products.

 * Each `name` resolves to a single self-contained SVG asset under `./assets/`.
 * The component fetches and renders that SVG into shadow DOM; the host's
 * dimensions follow the SVG's intrinsic `width`/`height`/`viewBox` exactly as
 * exported from Figma — so a future asset with non-standard dimensions
 * "just works" without a CSS contract change.
 *
 * Consumers that need to reserve layout space before the async fetch
 * resolves (e.g. above-the-fold marketing, dense grids) should wrap the
 * logo in a sized container — `mud-service-button` does this for its
 * `badge` slot (24 × 24).
