/*
 * Live text for the header bar and footer menu.
 *
 * Adobe Muse rasterised every navigation label into a 16px-tall (header) or
 * 20px-tall (footer) PNG, so the menu existed only as a row of images: nothing
 * for a crawler to read as site structure, nothing for a screen reader beyond
 * the alt attribute, and labels that softened whenever fit-layout.js scaled the
 * page. Each label's <img> has been replaced by a <span> holding the same words,
 * and the span keeps the image's Muse id, so every width, height and position
 * rule in the page stylesheet (and in header-nav-size.css) still applies. The
 * geometry is therefore untouched; only the paint changes.
 *
 * The type was recovered from the sprites themselves: profile the ink columns of
 * each label, render the same string in Chromium at 400px and scale linearly (a
 * 1:1 sweep only finds the edge of a hinting plateau, not the true size). Both
 * menus came back as Open Sans Semibold at the same rendered size:
 *
 *   header  ink widths imply 15.8px, and header-nav-size.css draws the bar 20%
 *           larger, so 15.8 x 1.2 = 19px in a 19.2px box
 *   footer  ink widths imply 18.9px in a 20px box -> 19px
 *
 * Colour is per item, not per menu, because Muse baked whatever it was given.
 * Read off the sprites: the footer is white throughout, the header is black
 * except on index.html, where it sits over the dark hero and is white. Every
 * link rolls over to #BC1818. The current page's label is a separate image with
 * no rollover, and it is only red on about-us, faq-s, how-we-work and
 * our-gaurantee - on contact-us and index Muse rasterised it in the ordinary
 * colour, so it does not stand out there either. Each label therefore carries
 * its own ink class rather than inheriting a menu-wide colour.
 *
 * The sprites are still on disk, so any label can be reverted by restoring its
 * <img>.
