/* Sembr public status page.
 *
 * Mobile first. This is the page somebody opens on a phone, standing up,
 * because something is not working.
 *
 * NO AMBER AND NO ORANGE, a standing Sembr constraint, and here it also happens
 * to be the accessible choice. The usual status triad of green, amber and red
 * is close to the worst possible palette for the most common colour blindness,
 * where red and green already collide. Degraded borrows the existing --calm
 * blue from feed.css rather than inventing a colour, so the four states are
 * green, blue, red and grey, and every one of them also carries a word. Colour
 * alone is never the status.
 *
 * Manrope is the Sembr typeface and is NOT loaded, deliberately. A page whose
 * job is to work when other things are broken should not depend on a font
 * origin it does not control.
