/* Teacher pages in the DT Classroom site theme (cream paper, navy ink, yellow accent).
   Used by /teacher-signin/, /teacher-accounts/ and the verify and reset pages. Loaded after teacher-security.css, so it restyles those components too.
   The page is natively light; dt-a11y.js turns it dark for the Dark choice and the contrast option still applies. */
