Starlight's `starlight-theme` key is the single source of truth,
so a choice made in docs carries to the marketing pages and back.
It stores dark | light | auto; we deliberately treat `auto` as
dark, because the default here is a presentation decision and
must not follow the reader's OS. The mock palette follows the
ground: solarized-light on paper, catppuccin on ink. */
