/*
 * otp-code.css — the one-time-code field (public/src/otp-code.js).
 *
 * Six painted boxes over ONE real input. Linked by login.html, index.html and
 * oauth-consent.html, so the field looks and behaves the same everywhere a
 * code is entered. A plain stylesheet on purpose: the consent page's CSP
 * (style-src 'self') refuses inline styles. Every value is a token each page
 * already defines, with a fallback for the one page that lacks it.
