1/**
2 * HomeRunner Toolkit — Lowest Rate Availability (frontend)
3 *
4 * Swaps the explorer card's price for a "No dates available" label on
5 * listings the module flagged as having zero bookable nights
6 * (payload key from config.flag, stamped server-side in Core.php).
7 *
8 * The explorer registers every grid instance on
9 * window.hrExplorer.instances and renders each card through the
10 * instance's getPropertyHtml(). Wrapping that method is the only
11 * per-listing hook the plugin exposes — its `no_dates_price` option is
12 * global, so suppressing the price there would blank every card on the
13 * site. The registry is wrapped in a Proxy so instances registered
14 * before OR after this script runs both get patched; card HTML itself
15 * is never produced before the explorer's first async fetch resolves,
16 * which cannot happen while footer scripts are still executing.
17 *
18 * Config (window.hrtkLraNoDates):
19 *   - label string  Label text (plain text; inserted via textContent).
20 *   - flag  string  Payload key marking a zero-availability listing.
