Dynamic color: keep card surfaces lighter than the page

In light mode surfaceContainerLow is slightly darker than the OS surface bg
maps to, so the selection bar and other cards blended into the page. Use
surfaceContainerLowest (light) / surfaceContainer (dark) for NooColors.surface.

+### Why PolyForm Shield?
+
+I want the code to be open to read, learn from, build, and improve, while
+keeping anyone from lifting it and shipping a competing copy of the app.
+Permissive licenses (MIT, Apache) allow exactly that, and copyleft ones
+(GPL) still allow a rebranded fork. PolyForm Shield sits in between: it is
+not an OSI "open source" license, and I'm not claiming it is, but it keeps
+the code available while protecting the project.
+
+## Where development happens
+
+The source of truth is a self-hosted Gitea instance, and this GitHub
+repository is a read-only mirror plus the public issue tracker. I keep it
+that way so that I own my hosting, builds, and release credentials rather
+than depending on a third party for them. You don't have to use Gitea:
+open issues and pull requests here as usual. Open PRs are imported to my
+instance, reviewed and merged there, and `main` is mirrored back here, so a
+merged PR may show as closed with a link to the commit instead of "Merged".
+See [`CONTRIBUTING.md`](CONTRIBUTING.md) for details.
