/*
 * SELECTED OFFER — a two-state system, and only two states.
 *
 *   unselected : 3% brand tint  + 1px brand at 35%   (a hairline)
 *   selected   : 8% brand tint  + 2px brand at full strength
 *
 * Both states are the brand colour; the selected one is simply the stronger
 * reading of it, in BOTH width and alpha. Nothing here is a hex value, so the
 * whole component follows the Customizer.
 *
 * WHAT KEEPS IT FROM SHOUTING, and what must stay this way:
 *
 *  - the tints are 3% and 8%. An earlier version of this component used a 12%
 *    fill plus a coloured drop shadow, and on a jewellery storefront the
 *    selected option shouted louder than the product photo beside it. Low
 *    alpha is what makes a brand-coloured card read as premium rather than
 *    heavy, and it is what keeps a dark brand colour usable here.
 *  - the weight does the work, not the fill. A 1px hairline against a 2px solid
 *    is unmistakable at a glance without either card needing a loud background.
 *
 * KNOWN, AND DELIBERATE: the border grows by 1px per side on selection, so a
 * selected card is 2px taller and the cards under it move down by 2px. Both
 * widths were 2px before precisely to avoid that; the 1px/2px pair is the
 * requested design. Do not "fix" it by padding the unselected card to
 * compensate — that changes the component's spacing, which is not ours to
 * change here.
 *
 * Three things are deliberately absent and must stay absent: no transition (the
 * state change is instant), no :hover (a hover tint makes a third state that
 * competes with "selected"; the pointer cursor is the affordance), and no
 * box-shadow.
