Note: building //web/src:styles on macOS needs sandboxed execution

It seems that the SassCompiler is not hermetic.

If you build //web/src:styles without sandboxed execution, it will fail with:

ERROR: yngdieng/web/src/BUILD.bazel:36:1: Compiling Sass failed (Exit 65)
Error: Can't find stylesheet to import.
  ╷
1 │ @import '@angular/material/theming';
  │         ^^^^^^^^^^^^^^^^^^^^^^^^^^^
  ╵

Target //web/src:styles failed to build

However, neither custom-theme.scss nor styles.scss is in the input for //web/src:styles.

For now I disabled --spawn_strategy=local in .bazelrc. This might lead to reduced build performance on macOS. (However not very significant as far as I can tell)
