/* Exercise action buttons (submit, try again, and the forward button, which is #submit
   relabelled by JS) show lowercase with a bold initial, matching the s/t/n key shortcuts.
   Yes/No keep their capitals, bold initial only. CSS only, so JS-set labels pick it up too.
   A static file, not inline in base.html: some tests assert the rendered page never contains
   certain words, and the selectors below spell one of them. */
