Side A implements substantial functional improvements to the vote comparison flow: it adds a dedicated chromeless fullscreen layout, updates the POST success path to morph both the new vote preview and edge history, normalizes and sorts vote ratios relative to the displayed left/right order, and includes new tests covering the sorting behavior and browser interaction. Side B is a valuable but narrowly scoped bug fix that defines `GITHUB_API_BASE_URL` with a default to prevent a `NameError` when the OAuth callback references the GitHub API base URL.
