/* helloContra design system.
 *
 * One stylesheet for the whole application, so Login, Dashboard, Customers,
 * Estimates and Invoices cannot drift into looking like different products.
 *
 * Conventions that matter for an accounting product:
 *   - Money uses tabular figures and is right aligned, so columns of numbers line
 *     up digit for digit and a wrong magnitude is visible at a glance.
 *   - Colour carries no meaning on its own. Every status pill has a word in it.
 *   - No animation beyond a hover transition. Ledger work is read, not watched.
