 *
 * Rule: a button is a filled, coloured shape. Never white on white.
 *
 * The old default was #f4f4f5 on a #fff card with a 1px grey border — which is
 * to say, invisible. "Change design" and "Full preview" were the two controls
 * people needed most and the two hardest to find on the page. A control that
 * has to be hunted for is broken however tidy it looks.
 *
 * Three jobs, three colours, and nothing else:
 *   btn          slate   — do a thing
 *   btn-primary  blue    — do the main thing here
 *   btn-go       green   — the payoff (print it)
 *   btn-danger   red     — destroy something
