/* Stock Guesser console — design system.
 *
 * Mobile first, in the spirit of Wealthsimple: warm off-white canvas, white
 * cards, near-black type, one big number per screen, hairline-separated
 * lists, pill buttons, green/red only for money moving. Dark mode follows the
 * OS. Pages compose these classes; page templates should need little or no
 * CSS of their own.
 *
 * Layout ......... .app (shell) · .page · .page-head · .stack · .grid-2/.grid-3
 * Type ........... .eyebrow · .title · .subtitle · .muted · .small · .num
 * Surfaces ....... .card · .card-head · .card-title · .card-link
 * Numbers ........ .hero (.hero-label/.hero-value/.hero-change) · .stats > .stat
 * Lists .......... .list > .row (.row-avatar · .row-main · .row-title · .row-sub · .row-end · .row-value · .row-meta)
 * Key/value ...... .kv > div > dt/dd
 * Status ......... .pill (+ .pos/.neg/.warn/.info/.dark) · .dot · .banner (+ .ok/.warn/.error)
 * Actions ........ .btn (+ .btn-primary/.btn-secondary/.btn-ghost/.btn-danger/.btn-sm/.btn-block) · .actions
 * Forms .......... .field (label · input/select/textarea · .hint) · .switch · .segmented
 * Tables ......... .table-wrap > table.table (td[data-label] stacks into cards on phones)
 * Misc ........... .empty · .tabs · .sheet (modal) · .skeleton · .chart
