 * The platform's summary (footfall) plus today's sales (money) → the card.
 *
 * `/api/dashboard/summary` carries no revenue or sales, so those are counted
 * from the same day's `/api/sales` rows. Summed in integer paise so a day of
 * ₹0.10s cannot drift, then turned into rupees here, once, so no component
 * ever divides by 100 itself.
 *
 * Enquiries and "on the floor now" have no source on the platform yet and are
 * `null` — the card shows "—" rather than a 0 that reads as a real answer.
