 * visitor standing outdoors in daylight, holding the phone in
 * one hand. That drives three decisions throughout —
 *
 *   - generous tap targets, never smaller than 44px
 *   - high contrast, since the alternative is squinting at a
 *     screen in the sun
 *   - the primary action low on the page, within thumb reach
 *
 * Inherits every colour and type token from main.css.

 * NO UNDERLINES.
 *
 * style.css turns link underlines off globally, but it is worth
 * being explicit on the components here: these links are cards,
 * buttons and navigation, where an underline reads as clutter
 * rather than as an affordance. The hover and focus states carry
 * the meaning instead — colour on text links, a gold border on
 * cards — so nothing is lost for anyone navigating by keyboard.
