 * Document Up Automat - front end.
 *
 * Mirrors the look of "Document Up Manual" (andrei-saguna/document-section):
 * same tokens (navy #002547, muted #5d6979, accent link, subtle borders),
 * same pill filters and bordered rows. Every token falls back to a plain
 * value so the block also renders correctly on themes without those presets.
