/*
 * The public landing page.
 *
 * Its palette is not chosen, it is inherited: every colour below is lifted from
 * packages/ui/src/theme/themes/ruoc.json, the app's own light theme. The page
 * exists to show the app, and a marketing site in its own colours would put a
 * screenshot of one product inside a page for a different one — the seam shows
 * most at the exact place the eye goes first.
 *
 * The type is Inter for the same reason: it is what the app sets, so the
 * headline above the screenshot and the text inside it are one voice. Both
 * weights are vendored rather than pulled from Google, because the people this
 * page is for are in Russia and a font that fails to load takes the page's
 * character with it.
