   Question of the Day — stylesheet
   Includes the site's shared header/footer styling (previously inlined
   per-page only on the main pages, and missing on the QOTD pages — this is
   why QOTD pages did not visually match the rest of drpraveendra.org).
   Keeping it here means every QOTD page stays in sync automatically.
