/*
 * Typing's page: the options bar at the top, the words in the middle (three
 * lines, a caret that glides), the hints at the bottom; the result takes the
 * words' place. The quiet grey of the letters still to type against the full
 * colour of the typed ones is the whole look, so everything else stays out of
 * the way: the bar and the hints fade while a test runs. Colours are the
 * panel's tokens, so both themes follow; the page is about 720 by 390 (560
 * wide in compact) and nothing scrolls.
