FLASHSALE

An animated countdown bar. Disappears entirely once end_time has passed. Supports two display modes via display_mode:

• "modal" (default) — tapping the bar opens a bottom sheet grid of products (fetched via the product query contract, rendered with the same rich product card as CAROUSEL).
• "inline" — products are fetched eagerly and rendered as a horizontally-scrolling row directly beneath the bar, carousel-style. The bar is no longer tappable in this mode.

{
  "type": "FLASHSALE",
  "params": {
    "title": "Flash Sale",
    "subtitle": "Grab it before time runs out",
    "end_time": 1782000000,
    "category_id": 75,
    "display_mode": "inline"
  }
}

• end_time — a Unix timestamp in seconds, or an ISO-8601 string. When omitted, the bar shows with no countdown and never expires.
• title / subtitle — shown on the bar and repeated in the bottom sheet header (modal mode only).
• display_mode — "modal" (default) or "inline", as described above.
• Every other field is forwarded to ProductQuery.fromParams to fetch the products — see product-query.md.

The bar itself animates a shifting red→orange gradient and a rotating "comet" border segment.
