/*
 * Koblime application UI — Library page and the book dialogs.
 * Mirrors docs/design/LIBRARY.html; every value comes from the tokens in vars.css.
 *
 * Views render into the light DOM and dialog renderers render into the overlay's
 * light DOM, so these rules reach both. Every rule is scoped to its host element
 * (`kob-book-list`, `vaadin-dialog-overlay[theme~='kob-modal']`) so the marketing
 * stylesheet and Bootstrap can never win by accident.
