Show a single centered loader without stat labels until all directory
stats resolve, using useFeedStateString like popular threads. Center
directory table status loading in its cell.
Accessibility/semantics pass aligned with React Doctor: role-based spans/divs become real buttons, role=status becomes <output>, modals use native <dialog>, author/peer flags render as <img>, and embed/challenge iframes are sandboxed. Includes review follow-ups: correct button chrome/centering/themed dialog colors and focus rings, the missing aria-label i18n keys (all languages), the Yandex image-search URL, clearer .bso setup steps, a keyboard-accessible image-search dropdown, and removal of the post-edit ('comment edited') display (mod edits unchanged).
Merge board directories from the new bitsocialnet/lists per-directory layout on the client side.
Update vendored fallback data, sync tooling, directory references, and tests.
Treat failed board stat fetches as complete on the home page so stats do not stay loading forever.
