3 * Booking Widget Math Reconcile — JS patch.
4 *
5 * The HR plugin's booking widget JS double-subtracts the weekly discount
6 * when `price_with_dates = average_price`:
7 *
8 *   actualPrice (strikethrough) = totalPrice / nights         CORRECT post-discount
9 *   price       (active bold)   = (totalPrice - discount) / nights   double-discounted
10 *
11 * `totalPrice` (rateplan.total or total - taxes) already has the discount
12 * applied server-side, so subtracting `discount` again on the JS side is a
13 * bug. Result: customer sees a per-night number lower than total/nights.
14 *
15 * Fix logic:
16 *   Let S = strike value (HR's actualPrice)  = totalPrice / nights
17 *   Let A = active value (HR's price)        = (totalPrice - discount) / nights
18 *   Then discount/nights = S - A, and
19 *        pre-discount per-night = (totalPrice + discount) / nights = 2S - A
20 *
21 * With showStrikethrough = true (default):
22 *   strike = (2S - A)  pre-discount per-night
23 *   active = S          post-discount per-night
24 *   matches the search results card's strike+active pair
25 *
26 * With showStrikethrough = false:
27 *   active = S, strike removed
28 *
29 * The JS is enqueued conditionally by Core::enqueue_frontend_patch (only
30 * when this module is enabled).
