* fix(comment-content): render reason text as comment content
* fix(post-form): use native browser styling for flash tag select
Exclude the flash tag dropdown from themed post-form select styling so it
renders with the browser's default select appearance, matching the flag selector.
* fix(p2p-stats): show peer flags for DNS6 relay hostnames
Extract embedded IPv6 addresses from dns6 multiaddrs so geo lookup and country flags work for relay peers that publish IPv6 via DNS hostnames.
* fix(flags): hide geolocation-only selectors on /int/ and /sp/
Country-only boards auto-publish geographic location flags without
showing a flag dropdown, matching existing /bant/ behavior.
* fix(embed): restore youtube thumbnails and file-row labels
Restore thumbnail-first previews for YouTube embeds in post media and markdown hover.
Desktop posts show File with the thumbnail image URL and a youtube video type label.
* fix(embed): address youtube thumbnail review feedback
Translate the youtube video label, handle mobile/music YouTube hosts as standard YouTube URLs, keep affected mocks current, and cap default Vitest workers to reduce local CPU spikes.
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).
