/*
 * Classivo application styles.
 *
 * Hand-written rather than Tailwind, deliberately. The marketing site has a
 * build step because it is a dozen pages of varied layout; the application is
 * a handful of dense screens used all day by the same people, and a stylesheet
 * with no build step means a fix is one file edit and a reload. It also keeps
 * the app deploy free of a Node/Tailwind dependency.
 *
 * The palette is lifted from the marketing site so the two look like one
 * product. Keep them in step by eye — there is no shared token file, and
 * inventing one for eleven colours would be more machinery than it saves.
