/**
 * The marketing site, in one stylesheet and no build step.
 *
 * The palette, the type pairing and the two-kinds-of-colour rule are lifted
 * from packages/design-blue rather than reinvented — brand and accent are
 * constants written as literal hex in both themes, and only the nine semantic
 * neutrals swap. A brand that shifts when someone flips the theme is not a
 * brand.
 *
 * No Tailwind here on purpose. This is four screens of static content; a build
 * pipeline to produce it would be more moving parts than the thing itself, and
 * a marketing page that cannot be edited without a toolchain is one that stops
 * being edited.
