 *
 * Rules this file sticks to:
 *  - Source order is reading order. With CSS off the page still reads correctly.
 *  - Nothing is conveyed by colour alone.
 *  - Focus is always visible, and never thinner than the thing it outlines.
 *  - Text scales with the visitor's browser setting (rem throughout, no px fonts).
 *  - Motion is opt-out, and there is very little of it to begin with.
