 * Touch targets
 *
 * The dashboard is reviewed on tablets as well as desktops, and the two want
 * different things: a mouse is pixel-accurate and rewards density, a fingertip
 * covers roughly 9mm and does not. So this is split in two.
 *
 * 1. Hit-area expansion, applied everywhere. A pseudo-element gives the small
 *    icon buttons a 44px target without changing how they look, so a desktop
 *    user sees the same dense UI while every pointer gets an honest target.
 *
 * 2. A `pointer: coarse` block, which is the tablet layout proper: controls
 *    actually grow, and anything that was revealed on hover becomes permanent,
 *    because a touch screen has no hover to reveal it with.
 *
 * 44px is the floor throughout (Apple HIG; Material asks 48, which the primary
 * controls below meet). Adjacent targets are kept at least 8px apart — a big
 * target that overlaps its neighbour just means confidently hitting the wrong
 * thing.
