/* Hero demo card.
 *
 * The call widget lives inline in the hero now instead of in a modal, so this
 * sheet styles a card rather than dialog contents. The audio logic is in
 * _DEMO_JS in app/landing.py and is unchanged: same WebSocket protocol, same
 * mu-law encode/decode, same per-device daily budget.
 *
 * .demo-call and .demo-hang are modifiers over the ported .btn-primary and
 * .btn-danger, so they inherit the brand colors and hover states. Only layout
 * is overridden here.
