Changed
- One place decides what the product looks like. The palette now comes from
design/tokens.css, the design guide's token source, instead of being decided
in the shared shell. Every page — the review workspace, the story map, the
spec tree, the build board, the chooser — picks up the guide's Cavalry brand:
purple-cast neutrals in place of the cool greys, and the brand red at the step
that holds its contrast on white. Nothing moved and nothing was renamed; only
the colours changed. - Dark is now part of that source rather than something the shell decided on its
own, so both themes come from the same place.
