// ── Issue 2: Sortable Amount and Status columns ──────────────────────────────
// ── Issue 3: ABI Explorer keyboard navigation (static/DOM note) ───────────────
//
// Full keyboard navigation (focus, arrow keys, Enter/Space) is tested through
// abi-explorer.html's inline <script>. A unit note is recorded here for
// traceability; interactive keyboard behaviour should be verified manually
// or with an end-to-end test runner (e.g. Playwright).
//
// The items verified statically below confirm the rendered markup satisfies
// the accessibility requirements without requiring a running browser.
