/* Jelly chips -------------------------------------------------------------
 * A port of React Bits' Jelly Radio (reactbits.dev/micro/jelly-radio) at
 * gap 4, barge 0. Upstream is a radio group driven by clicks; these chips are
 * links, so hover takes the place of selection: the hovered chip swells and
 * opens to show its label while its neighbours barge aside and shrink.
 *
 * The springs live in js/jelly-chips.js; these rules only describe the resting
 * shape. The paper layout carries its own inlined copy of both, because paper
 * pages are standalone and load none of the theme's assets.
