/*
 * The document intake review screen: a queue on the left, one entry in focus on the right.
 *
 * Every token here is one dok-theme.css actually defines. The first version of this file was written
 * against a vocabulary that does not exist in this product — --dok-border, --dok-surface,
 * --dok-surface-hover, --dok-text-muted, --dok-primary, --dok-space-4 — and CSS fails a declaration
 * silently when a custom property is undefined and has no fallback. So `border: 1px solid var(--dok-border)`
 * produced NO border and `background: var(--dok-surface)` NO background: the screen rendered as bare text
 * on the page, with the panels invisible and the section headers floating. It looked like a missing design;
 * it was a missing variable.
 *
 * The palette is the same one the rest of the app uses: --dok-card-* for containers, --dok-text-* for type,
 * --mud-palette-* for accents (there is no --dok-primary; MudBlazor owns the brand colour and follows the
 * light/dark theme, which a hardcoded hex would not).
