Package apply executes the reviewer's verdicts against the git working tree: approved items are left alone, rejected items are reverted (via `git checkout <base_ref> -- <path>` for tracked files, or `os.Remove` for untracked-added files).

Package config loads and validates the per-project snapdiff.toml.

Package gallery enumerates all snapshot PNGs in a repository's working tree (subject to the configured globs).

Package gitscan enumerates snapshot diffs in a git repo: files matching configured globs whose content differs between a base ref and the working tree (or which are untracked / deleted).

Package imdiff renders a per-pixel highlight overlay PNG comparing a baseline image to a current image.

Package lifecycle owns the daemon shutdown sequence: once the reviewer finalizes the session, linger briefly so the browser can render the success state, then gracefully shut down the HTTP server.

Package review holds the in-memory state for one review cycle: the list of diffed snapshots, per-file verdicts, and a "done" signal channel closed when the reviewer hits Finalize.

Package web wires the chi router, templ views, and static assets that make up the snapdiff review UI.
