 * NOTE:
 * - The use of browser-specific styles (-moz-, -webkit-) should be avoided.
 *   If used, they may not render correctly for people reading the email in
 *   a different browser than the one from which the email was sent.
 * - The use of state-dependent styles (like a:hover) don't work because they
 *   don't match at the time the styles are made explicit. (In email, styles
 *   must be explicitly applied to all elements -- stylesheets get stripped.)
