/*
 * Holo family bw-reverse: Black & White reverse holos.
 *
 * Scope: the reverse holos js/fam/bw-reverse.js claims: 1,072 prints of bw1-bw11 that have their own foil mask (99 of Dragons Exalted's 112).
 * Cards: the faces js/fam/bw-reverse.js claims; it adds `fam-bw-reverse` to them, and every rule below is scoped to it.
 * Specificity: body.fx-holo.fx-holo.fx-holo .tcg.era-bw.(x5).fam-bw-reverse.(x4) beats the era sheets
 * (this sheet loads after them); keep the era's :not(.lit):not(.settling) when overriding a rest-state rule.
 * Part of the older-era holo remaster (2026-10-01): the research, photos and review for this family are in
 * /mnt/project-files/holo-remaster/bw-reverse/.

/* ---- What this sheet does ------------------------------------------------------------
   1. js/fam/bw-reverse.js gives each print its OWN foil mask (`--bw-layout`, cut from TCG Live's map): the era's reverse rule
      (css/holo/bw.css `.bw-rev .foil`) intersects it with `--art`, so the foil sits exactly where the real reverse is foil
      (the art window, the symbols and the ink stay matte: the mask also cuts the body text's dark ink out of the foil, from the print's own scan;
      review #2 found an overlay tinted every dark or grey letter).
   2. The sheen (review #1: the era look plus a small lift was imperceptible, +2 to +8 levels, and a bigger colour-dodge only washed the text box
      to white and bleached the ink). The real reverses are mottled coloured bands over the body colour (Collexy scans of Emboar 20, Blitzle 40,
      Lillipup 81), so the layer now blends with OVERLAY: a light body takes the tints and the flash, dark ink stays dark (overlay doubles a dark
      pixel at most; colour-dodge lifted it to red and cyan). Tile x saturated spectrum band x pointer pool, as the era, with the filter
      raised so the product sits around the overlay's neutral grey.
   Rainbow speed (Noah, 2026-10-02): the band is 260% of the card, a 100deg gradient whose two spectrum cycles each take 50% of the 3.19-card
   gradient line (period 1.6 cards); the pointer moves it 1.6 cards across a full horizontal sweep (0.99 spectrum), at most 1.2 on a
   corner-to-corner sweep. Under the 1.5 limit. */
