 * Ready for the Oath styles.
 * Brand motif: a row of rounded tiles, like an answer sheet. The home page shows the real test's pass mark
 * as 20 tiles with 15 filled; progress and results use the same row:
 * cobalt = answered or right, amber = the current question, outlined = still to go, red outline = missed.
 * Type: a DIN-style signage face for headings and numbers (system fonts only, nothing downloaded),
 * the system UI face for reading.
