No credentials or accounts are needed — the extension has no login and collects no data.

How to test:
1. Click the Rollare Bracket Maker toolbar icon — the generator opens in a new tab.
2. Left panel: pick a format (single elimination / round robin), set team count (2–16), enter names (or Shuffle), then "Generate bracket".
3. Click a team to record a winner; winners advance automatically. With 4+ teams a third-place match appears below the final.
4. Header buttons export the bracket as PNG or copy it to the clipboard.
5. "Preview all 6 formats" plays animated format demos; each card links to rollare.com.

Quick demo states (no manual input): open the extension page and append ?demo=se-picked (winners pre-filled + third-place match) or ?demo=rr (round robin with standings) to the app.html URL.

Build/source: bundled with WXT (open-source build tool) from unobfuscated TypeScript sources; reproducible with "bun install && bun run build:firefox". Source archive can be provided on request.

Note on validator warnings: any remaining innerHTML references come from the bundled react-dom library internals; the extension never injects untrusted content into innerHTML. The UI follows the browser language (English / 简体中文 / 日本語 / 한국어).
