/*
 * Scarlet & Violet finishes that many sets share, so every set's cards draw
 * them the same way: Tera ex and ACE SPEC. Both need the card's TCG Live foil
 * map (js/foil-maps.js), so foilPattern() in js/app.js only adds their class
 * when a map ships, and a set without maps keeps the older recipes.
 *
 * - Tera ex (Double Rare and Ultra Rare cards with the Tera subtype). TCG Live
 *   prints them SV_ULTRA / ETCHED, the same foil as a Special Illustration
 *   Rare (its print ids end DoubleRareC / UltraRareC): the whole card is foil,
 *   the Pokémon at part strength, with a fine etched grating cut with
 *   four-point sparkles. The crystal facets are ink over that foil; the map's
 *   grey steps keep them faceted under the shine.
 * - ACE SPEC Rare: ACE_FOIL / ETCHED. A crosshatch holo that collectors
 *   likened to the Sword & Shield Radiant pattern when it was revealed
 *   (PokeBeach, January 2024): hot pink stock that stays pink, cyan metal
 *   banners, a rainbow art window, and fine horizontal ridges everywhere.
 *
 * Layer ideas follow pokemon-cards-151's special illustration rare and
 * pokemon-cards-css's radiant holo by Simon Goellner (@simeydotme), GPL-3.0;
 * see NOTICE.md. The research is in the card-textures skill,
 * .claude/skills/card-textures/reference/sv-tera-acespec.md.
 *
 * Each finish rides on a second class next to the older pattern class
 * (`foil-ex foil-tera`, `foil-ultra foil-tera`, `foil-holo foil-acespec`), so
 * the Classic engine is untouched. The doubled class outranks the
 * three-class map rules other sheets add for `.foil-ultra` and friends,
 * whichever order the sheets load in. Loaded after celebration.css.
 *
 * Rest state (PR 5): a resting card paints `.foil` alone; the pseudo layers
 * and `.glare` only exist while a card is held or settling.

/* ---- ACE SPEC Rare: ACE_FOIL / ETCHED ---------------------------------------
   Retuned against Surging Sparks photos (2026-09-27): the magenta body stays
   saturated hot pink at every angle and never goes silver; the ACE SPEC
   banners are a separate cyan metal; the art window runs the full rainbow
   with X and diamond facets (Deluxe Bomb); and fine horizontal ridges cross
   the whole card, visible even unlit.

   Everything that shines is a colour-dodge on `.foil`, masked by the map:
   a dodge lifts the channels the print already has, so the magenta stock
   (empty green channel) only gets hotter pink, the cyan banners (the map's
   full-strength zone) turn bright cyan metal, and the art window takes the
   whole spectrum. `.foil` stacks the ridges over a rainbow cut into a
   crosshatch lattice (pokemon-cards-css's radiant holo bars, crossed with
   `lighten` so the lattice lines are the bright ones); `::after` runs the
   rainbow through the etch map's line fields; `::before` is the sparkle
   grain. The glare darkens away from the light, and its `::after` only
   brightens the ridges near the light, never a white wash. */
